Cocoa Core (aka NSDate) is the number of seconds (32-bit value) since 01 Jan 2001. The 64-bit version is the number of nanoseconds since 01 Jan 2001.
Unix Time
This is a 32-bit integer holding the number of seconds since 01 Jan 1970. The 64-bit integer version holds the number of milliseconds since 01 Jan 1970.
Windows COM
Windows [Component_Object_Model COM] stores date time in a double (floating point) number representing the number of days since 30 Dec 1899.
Windows FILETIME
A 64-bit integer containing the number of 100-nanosecond clock ticks since 01 Jan 1601.
