The Linux/UNIX gettimeofday() function reports the time in the current Epoch. That Epoch is defined as starting "00:00:00 UTC, January 1, 1970"
C# provides a DateTime interface with a similar concept of time in the current Epoch. Just to make life interesting, C# defines the Epoch as being "12:00:00, January 1, 0001". (Note the mysterious absence of UTC in that start...)
This is, of course, just some offset. My problem is that I am trying to find out if the offset is some agreed international standard.
I don't think it is - it is operating-system dependent.

This is what I fear.
This question has arisen because we I am integrating some fancy Danish reflection measurement device into our Linux apps. The data provided by these devices is timestamped with UTC time - encoded with the C# DateTime functions, e.g., 5246315282908540247, which must have been around 1400 UTC today.
Just wondering - why not just stick to UTC timestamps, and ignore the Epoch?
I could pass the response to the Danes who made the device. They are already wondering why I use Linux. That tells a bit...
