I am looking to use this plugin: http://keith-wood.name/countdown.html
but I need to use the TimeZone feature of it. So I was looking at the sample code
$('#sydneyCountdown').countdown({until: liftoffTime, timezone: +10});
so +10 is the TimeOffSet number. Now I need to make it so I can do a jquery get request and grab the TimeOffSet from the server(which gets the users time from the db and does TimeOffSet).
However it seems that C# TimeOffSet returns something like this "+02:00"(not this is just a random zone not the same as the one in the jquery example).
So it seems like all the C# TimeOffSet follow that format +/-xx:xx
So I don't understand why the jquery plugin is only 2 digts while the other one is 4 digits.
Can I know off safley the last 2 digits in the C# tomatch the plugin format?
Edit - would this work?
// working on how to get offsetTime will be posted soon.
string time = "-08:30";
string[] split = new string[] {":"};
string[] splited = time.Split(split, StringSplitOptions.RemoveEmptyEntries);
int hours = Convert.ToInt32(splited[0]);
int mins = Convert.ToInt32(splited[1]);
int totalMins = (hours * 60) + mins;
So just convert the hours to mins and then add the mins to it?
Edit - With offSetTime
var info = TimeZoneInfo.FindSystemTimeZoneById("Tokyo Standard Time");
TimeSpan span = info.BaseUtcOffset;
string time = Convert.ToString(span);
string[] split = new string[] {":"};
string[] splited = time.Split(split, StringSplitOptions.RemoveEmptyEntries);
int hours = Convert.ToInt32(splited[0]);
int mins = Convert.ToInt32(splited[1]);
int totalMins = (hours * 60) + mins;
Problem though OffSet only gives me the number not the +/- sign. So I don't know how to get it.
Edit -
Never mind I it makes sense that they don't add the plus sign since I was just testing one that would have a "-" sign and it is shown.
The plugin says:
Cater for time zones with the timezone
setting, which is set to the target
time's offset from GMT, in either
hours or minutes.
So, I think based on the magnitude of the timezone value, it treats it either as hours or minutes. You should convert the <sign><hh>:<mm> format to into number of minutes, to account for timezones that are not hour-aligned. Something like:
var tz = "-08:30";
var tz_tokens = /([+\-])0?(\d+):(\d+)/.exec(tz);
var tz_minutes = (tz_tokens[1] + 1) * (tz_tokens[2] * 60 + tz_tokens[3]);
// ..., timezone: tz_minutes, ...

I want to parse the following input "10:05" in format "minutes:seconds" in seconds. So 10:05 should be 10 * 60 = 600 + 5 = 605. How can I manage to do this with code ?
Just split the string, parse the numbers, and do your calculation:
string s = "10:05";
var parts = s.Split(':');
int seconds = int.Parse(parts[0]) * 60 + int.Parse(parts[1]);
Console.WriteLine(seconds); // 605
You can also use TimeSpan.Parse in this case which is able to parse this format if you add a hour part in front of it. You can then use the TotalSeconds property to get your desired result:
double seconds = TimeSpan.Parse("00:" + s).TotalSeconds;
Console.WriteLine(seconds); // 605
#poke is close, but you asked for seconds, thus:
string s= "10:05";
double seconds = TimeSpan.Parse("00:" + s).TotalSeconds;
Returns 605.
There are many ways to do this. Here are just a couple. If you know that the format is always going to be mm:ss then you could use the TimeSpan class, the ParseExact method, and the TotalSeconds property. Here's an example of how you could do it.
TimeSpan ts = TimeSpan.ParseExact(mytime, "mm:ss", System.Globalization.CultureInfo.InvariantCulture);
double seconds = ts.TotalSeconds;
If you have a bunch of different formats that can show up you can use the ParseExact and provide multiple time formats. Here's an example that takes a few formats.
//HH -> 24 hour format always with 2 digits ("08" = 8 hours)
// H -> 24 hour format with as few digits as possible ("8" = 8 hours)
//mm -> minutes always with 2 digits ("08" = 8 minutes)
// m -> minutes with as few digits as possible ("8" = 8 minutes)
//ss -> seconds always with 2 digits ("08" = 8 seconds)
// s -> seconds with as few digits as possible ("8" = 8 seconds)
string[] formats = new string["HH:mm:ss", "H:mm:ss", "mm:ss", "m:ss", "ss", "s"];
TimeSpan ts = TimeSpan.ParseExact(mytime, formats, System.Globalization.CultureInfo.InvariantCulture);
double seconds = ts.TotalSeconds;
Here's a link to the MSDN documentation for the TimeSpan class. Check out the Methods and Properties for the TimeSpan class. Here's a link on formatting time strings.
The other way is to manually split the input string into the two parts and use the Convert class to convert each part into integers or doubles.
string[] timeparts = mytime.Split(':');
string minstr = timeparts[0];
string secstr = timeparts[1];
int mins = Convert.ToInt32(minstr);
int secs = Convert.ToInt32(secstr);
int seconds = mins * 60 + secs;
Here's the documentation for the Convert class.
I need to convert
20141013T155544.673-04/0
To a DateTime type.
Presently I am manually parsing the string out
//20130605T154727.683-04/0
//20130806T143808.018-04
//var a = new DateTime();
var year = segmentDate[0].ToString(CultureInfo.InvariantCulture) + segmentDate[1].ToString(CultureInfo.InvariantCulture) + segmentDate[2].ToString(CultureInfo.InvariantCulture) + segmentDate[3].ToString(CultureInfo.InvariantCulture);
var month = segmentDate[4].ToString(CultureInfo.InvariantCulture) + segmentDate[5].ToString(CultureInfo.InvariantCulture);
var day = segmentDate[6].ToString(CultureInfo.InvariantCulture) + segmentDate[7].ToString(CultureInfo.InvariantCulture);
//s[8] == "T";
var hours = segmentDate[9].ToString(CultureInfo.InvariantCulture) + segmentDate[10].ToString(CultureInfo.InvariantCulture);
var minutes = segmentDate[11].ToString(CultureInfo.InvariantCulture) + segmentDate[12].ToString(CultureInfo.InvariantCulture);
var seconds = segmentDate[13].ToString(CultureInfo.InvariantCulture) + segmentDate[14].ToString(CultureInfo.InvariantCulture);
string milliseconds = null;
if (segmentDate.Contains("."))
milliseconds = segmentDate.Split('.')[1].Split('-')[0];
if (milliseconds != null && milliseconds.Contains((" ")))
{
milliseconds = milliseconds.Split(' ')[0];
}
var offset = Convert.ToInt32(segmentDate.Split('-')[1].Split('/')[0]);
var a = new DateTime(Convert.ToInt32(year), Convert.ToInt32(month),
Convert.ToInt32(day), Convert.ToInt32(hours), Convert.ToInt32(minutes),
Convert.ToInt32(seconds), Convert.ToInt32((milliseconds ?? "0"))).AddHours(offset);
But that is a bad idea - and I cannot believe that this format isnt specified somewhere (that I have been able to find).
Any help is appreciated.
Thank you!
Update
4 digit year
2 digit month
2 digit day
T - denotes start of the time portion
2 digit hour
2 digit minute
2 digit second
. - denotes start of MS
3 digit ms
TZ offset (-04)
/0 I believe is offset minutes

So I have been playing with TryParseExact and ParseExact - and cannot come up with a format string that will pull this into a DateTime/DateTimeOffset type.
I also consulted with the supplier of this value and they also have a manual process to parse it out, like I posted already.
I cannot accept that this is the only way to achieve the desired result, and as such, will continue to play with it.
But if anyone else has suggestions, they are welcome here.
Here's the closest I've gotten:
string s = "20141013T155544.673-04/0";
var dt = DateTime.ParseExact(s,"yyyyMMddTHHmmss.fffzz/0",CultureInfo.InvariantCulture);
If the /0 represents minutes (and can be 0 or 30 then you could do a little manipulation to convert that to a "standard" time zone indicator:
string s = "20141013T155544.673-04/30";
string s2 = s.Replace("/0",":00").Replace("/30",":30");
var dt = DateTime.ParseExact(s2,"yyyyMMddTHHmmss.fffzzz",CultureInfo.InvariantCulture);
my application in c# is on payroll management system...and i would like to have the work hours of each employee in variable ...for this i m using double ...suppose an employee works for 8 hours and 20 min ..then the entry will be like 8.20 in text box...so i am separating the part before decimal in one variable using`
var values = totaldays.ToString(CultureInfo.InvariantCulture).Split('.');
int firstno = int.Parse(values[0]);
int secondno = int.Parse(values[1]);`
so i m getting first variable accurately but if part after decimal contains zeros it not storing in "secondno" variable . the zeros get eliminated automatically and the result for 8.20 and 8.2 is same i.e., 8.2 .
but since the time is different one is 8 hours 20min and other is 8 hours 2min ..i want some solution to to do this ..please help me since my whole application is dependent on this.
If the user is entering hours and minutes, why not use a TimeSpan?
var input = "8.20";
var time = TimeSpan.ParseExact(input, #"h\.mm", null);
var hours = time.Hours; // 8
var minutes = time.Minutes; // 20
Further Reading
Custom TimeSpan Format Strings
If you really must store it as a decimal first, you can still manage using this:
var input = 8.20m;
var parts = input.ToString("0.00", CultureInfo.InvariantCulture).Split('.');
var hours = int.Parse(parts[0]); // 8
var minutes = int.Parse(parts[1]); // 20
But as Ellesedil points out, you'll have to decide how to handle values like 8.70.
Try something like this. This is off the top of my head:
int hours = Math.Floor(totaldays);
int minutes = (totaldays - Math.Floor(totaldays)) * 100;
You can just format double with f2 format specifier
double d = 8.20;
string str = d.ToString("f2", System.Globalization.CultureInfo.InvariantCulture)
int hour = int.Parse(str.Split('.')[0]);
int min = int.Parse(str.Split('.')[1]);
thats it you are done
I want to show in a TextBox only hour and minutes
var test = dataRow.Field<TimeSpan>("fstart").ToString();
//test ="08:00:00"
var tb = (TextBox) gridViewRow.Cells[2].FindControl("fstart");
tb.Text = test;
how to show only hours and minutes "hh.mm"
You need to convert your data to TimeSpan and then use format:"hh\:mm"
string test ="08:00:00";
TimeSpan ts = TimeSpan.Parse(test);
Console.Write(ts.ToString(#"hh\:mm"));
In your case:
var test = dataRow.Field<TimeSpan>("fstart").ToString(#"hh\:mm"));
Remember to escape the colon :
You may see: Custom TimeSpan Format Strings
There is no need to convert from hh.mm.ss to hh.mm. TimeSpan is stored as a number of ticks (1 tick == 100 nanoseconds) and has no inherent format. What you have to do, is to convert the TimeSpan into a human readable string! This involves formatting. If you do not specify a format explicitly, a default format will be used. In this case hh.mm.ss.
string formatted = timespan.ToString(#"hh\.mm");
Note: This overload of ToString exists since .NET 4.0. It does not support date and time placeholder separator symbols! Therefore you must include them as (escaped) string literals.
The usual way of formatting strings seems not to work for some odd reason (tested with .NET 3.5). (It does not make any difference whether you escape the separator symbol or not):
var timespan = TimeSpan.FromSeconds(1234);
string formatted = String.Format(#"{0:hh\.mm}", timespan); // ==> 00:20:34
However, you can construct the string like this
string formatted =
String.Format("{0:00}.{1:00}", Math.Floor(timespan.TotalHours), timespan.Minutes);
or starting with VS2015 / C# 6.0, using string interpolation:
string formatted = $#"{timespan:hh\:mm}";
You can use TimeSpan methods:
ToString("hh':'mm")
// or
ToString(#"hh\:mm")
Also check all available formats here http://msdn.microsoft.com/en-us/library/8kb3ddd4.aspx
var test = dataRow.Field<TimeSpan>("fstart").ToString("hh.mm");
//test ="08:00"
var tb = (TextBox) gridViewRow.Cells[2].FindControl("fstart");
tb.Text = test;
I know this is a very old question. If anyone wants to show single-digit hours when your hours are a single digit then you can use
var hoursWithMinutes = TimeSpan.FromHours(hours).ToString(#"h\:mm")
This way, when your hours are double-digit I mean greater than 9 then it will be showing 10:00 something like that.
The previous solutions don't run if hours>24, try this solution if you have time in minutes very big
int minutes = 159000;
TimeSpan t = new TimeSpan(0, minutes, 0);
String HOURS = Math.Round(t.TotalHours, 0).ToString();
if (HOURS.Length==1)
{
HOURS = "0"+HOURS;
}
String MINUTES = t.Minutes.ToString();
if (MINUTES.Length == 1)
{
MINUTES = "0" + MINUTES;
}
String RESULT = HOURS + ":" + MINUTES;
You can achieve this by:
var hhmm = TimeSpan.FromMinutes(minutes).ToString(#"hh\:mm")
I have done the following piece of code to add the Hours and thus calculate total number of hours.
string hour1="48.40";
string hour2 = "45.35";
TimeSpan ts = new TimeSpan(int.Parse(hour1.Split('.')[0]),int.Parse(hour1.Split('.')[1]),
0);
TimeSpan ts1 = new TimeSpan(int.Parse(hour2.Split('.')[0]),int.Parse(hour2.Split('.')[1]),
0);
Double total = (ts.TotalHours) + (ts1.TotalHours);
The problem here is when i add hour1 and hour2 the total comes as 64.25 which actually should have been 64.15
This is just one of the test case, if i put hour1= 40.00 and hour2= 40.10 than the value in the total comes as 80.166666666666657 which actually should have been 80.10
can anyone help me understand what am i doing wrong and what is the correct way to add HOUR and get total number of hours ?
Actually you're getting correct result - just mixing minutes and fractional parts of hours.
80 hrs 10 mins is 80 1/6 hours
64 hours 15 mins is 64 1/4 hours
It gets a little strange when you have timestamps put into strings. But if you need to do it like this, this code should work
string hour1="48.40";
string hour2 = "45.35";
//find total number of minutes for each hour above
int minutes1 = int.Parse(hour1.Split('.')[0])*60+int.Parse(hour1.Split('.')[1]);
int minutes2 = int.Parse(hour2.Split('.')[0])*60+int.Parse(hour2.Split('.')[1]);
//calculate back to hours and minutes and reassemble as a string
string result = (minutes1+minutes2)/60+"."+(minutes1+minutes2)%60;
And I hope you are expecting 94.15 and not 64.15 in your example above.
You may use next code to get result you would like to:
string hour1 = "48.40";
string hour2 = "45.35";
TimeSpan ts = new TimeSpan(int.Parse(hour1.Split('.')[0]), int.Parse(hour1.Split('.')[1]),
0);
TimeSpan ts1 = new TimeSpan(int.Parse(hour2.Split('.')[0]), int.Parse(hour2.Split('.')[1]),
0);
TimeSpan total = ts + ts1;
int hours = (int)total.TotalHours;
int minutes = total.Minutes;
