Question

Answer 1

+6 A:

isnt that the datetime in ~~ticks~~ Unix time?

edit: yes it is: http://www.epochconverter.com/

You can make a DateTime by adding those seconds to a new date.

DateTime d = new DateTime(1970, 1, 1, 0, 0, 0)).AddSeconds(1280833200)

The "ticks" in a .NET timestamp are "the number of 100-nanosecond intervals that have elapsed since January 1, 0001 at 00:00:00.000 in the Gregorian calendar" according to http://msdn.microsoft.com/en-us/library/z2xf7zzk.aspx, which is not the same measurement or epoch as a Unix timestamp.

Nope, a tick is 100 nanoseconds, and the 'epoch' is the year 1. 1280833200 is a Unix timestamp (seconds since midnight on 1970-01-01).

@p.campbell why did you edit a wrong answer to fix it instead of just upvoting a correct answer?

Answer 2

+2 A:

This is a Unix timestamp; number of seconds since Jan 1, 1970. You can convert like:

DateTime epoch = new DateTime(1970,1,1);
DateTime ts = epoch.AddSeconds(1280833200);

@foz I think I beat Richard by about 30 seconds, actually . . . but I'm glad you accepted a correct answer :)

Bob 2010-09-03 14:46:11

not sure, I remember seeing yours said it was a minute later! anyhow, thanks to both of you.

Answer 3

+3 A:

It's Unix time - the number of seconds since midnight UTC on 1st January 1970. You can use this site to convert the timestamp to an ordinary date and time.

As for conversion in C#, this should work:

double timestamp = 1280833200;
DateTime dateTime = new DateTime(1970, 1, 1, 0, 0, 0, 0);
dateTime = dateTime.AddSeconds(timestamp);

Cheers, First CORRECT answer :-) much appreciated
