Global Mapper SDK
Retrieves the UTC time of the last GPS fix along with optionally any fractions of a second with the time. Most device will report positions every second so this would be 0.0 for most devices, but some high-frequency reporting devices will provide updates multiple times a second, in which case the fractional seconds value will be non-zero. Will return GM_Error_GPSDataNotValid if there if either we are not tracking a GPS device or the time is not known.
