Convert UNIX timestamp to .NET DateTime ticks in unmanaged code (no use of .NET)

Question

I need to "construct" .NET DateTime values in Python / C ++.

How can I calculate the number of ticks stored in a DateTime starting at a UNIX timestamp?

The solution using the Win32 API calls it ok (I believe the FILETIME functions can help).

This will give you the number of ticks since Unix Epoc started (which is 621,355,968,000,000,000)

(new DateTime( 1970,1,1) - DateTime.MinValue).Ticks

This gives you ticks per second (which is 10,000,000)

TimeSpan.TicksPerSecond

Just math from there (might bump into weirdness around jump seconds).
