问题
I need to "construct" .NET DateTime values in Python/C++.
How can I compute the number of ticks stored by DateTime starting from a UNIX timestamp?
A solution involving Win32 API calls it's ok (I believe FILETIME functions could help).
回答1:
This would give you the number of ticks since that the Unix Epoc starts at (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 (may run into weirdness around leap seconds).
