File Times
A file time is a 64-bit value that represents the number of 100-nanosecond
intervals that have elapsed since 12:00 A.M. January 1, 1601 Coordinated
Universal Time (UTC).
This decision makes it much easier to count leap years, no?

Will do that next week. Still need to make gcc work with my library.
