[App_rpt-users] Trimble GPS Date Bug

[Tim Sawyer]

This bug has been squashed by Chuck Henderson and Lee Woldanski. RTCMs now
correct for the 1997 date from Trimble GPS units. Thank you guys for saving
our bacon! Version 1.51 images are available at
https://github.com/AllStarLink/voter/tree/master/board-firmware. These
images will work on non-GPS or Garmin connected RTCMs but there's no reason
to update those units.
