I am wondering if .NET contains a method to convert the current time in seconds or milliseconds to a UNIX timestamp (offset from 1970/1/1)?
you can get the ticks from 1970 (ie the UNIX timestamp) like this:
TimeSpan timeSpan = DateTime.UtcNow - new DateTime(1970,1,1,0,0,0); double unixVersion = timeSpan.TotalSeconds;
