The date time used by the Global Positioning System (GPS) is normally expressed as a week number and a seconds-of-week.
This software can convert the GPS week-seconds format into the equivalent local date time and UTC date time, and vice-versa.

Because this software calculates GPS time from system time, it does not use GPS chip time.

Leap second incorrect

The leap second is fixed at 19. Should either be corrected to 18 or the field made modifiable.
