Can one of the Dev's of Mission Planner please have a look at this error.

After the 1.3.50.1 release of Mission Planner, I can't Georeference my photos anymore.

I've followed the workflow a couple of times previous to the release and it worked without any issues. 

My workflow is:

1. Sync camera to local time before I go out to the site.

2. Take a photo of the actual local time before the flight.

3. Determine the difference (Camera time - actual time) from the photo I took just before the flight.

4. In the geo ref tool of Mission Planner, Specify the log file and image folder, and use 'Time Offset' and enter the second in the 'Seconds offset' box.

I guess it is somehow trying to subtract the number of seconds from C#'s DateTime.MinValue in stead of the actual date/time, because it only give the error for positive numbers and the estimated time difference is  -63643572421.5266 s (which is roughly the difference between now and 1 January 0001.) 

I get this error.
