A GUI utility to compute calendar date, GPS time, Julian day, and day of the week

File Information
Description	This GUI will allow you to quickly and easily compute the GPS time and week number (modulo 1024) of a given (Gregorian) calendar date. It will also allow you to do the reverse operation of computing the calendar date, given the GPS time. Both calculations will display the Julian day and the day of the week. The screen shot shows the results of computing GPS time at the GPS birth date (midnight of January 5, 1980) Generated on Windows platform, not sure if compatible other OS.
MATLAB release	MATLAB 7 (R14)

Updates
18 Jul 2007	Julian date calculation was off by 0.5 days, even though GPS time and day of week calculations were "adjusted" accordingly.
15 Aug 2007	When computing calendar date from GPS time, needed to add 0.5 days to the calculation to obtain the correct result
10 Sep 2007	When computing a calendar date from GPS time, fixed the issue of a 12 hour offset in the time of day calculation
