You can use SQLite for this purpose (instead of C) as described in
http://www.sqlite.org/cvstrac/wiki?p=DateAndTimeFunctions.
I don't use C under Microsoft so I can't help you there (I only use C under
Linux).
I do know that making Jan 1, 1970 00:00:00 the same as 0 seconds, you could
write your own C subroutine to convert from DHMS2SEC (i.e. from Gregorian
hour minute seconds) to seconds and viceversa, SEC2DHMS.
