I have had look around stackoverflow, and even looked at some of the suggested questions and none seem to answer, how do you get a unix timestamp in C#?

You get a unix timestamp in C# by using DateTime.UtcNow and subtracting the epoch time of 1970-01-01.

e.g.

Int32 unixTimestamp = (Int32)(DateTime.UtcNow.Subtract(new DateTime(1970, 1, 1))).TotalSeconds;

DateTime.UtcNow can be replaced with any DateTime object that you would like to get the unix timestamp for.

There is also a field, DateTime.UnixEpoch, which is very poorly documented by MSFT, but may be a substitute for new DateTime(1970, 1, 1)
