Phade,
Proof 3? (Model 63053 Date: M08D06Y2015)
Per Steve D.s comments, I followed the directions exactly with the date/time procedure. All works OK until I try to save the TIMESTAMP.TXT file to the card and I get a write error. Happens with any SD card (freshly formatted), in the SD slot or in a SD adapter in the USB port. I thought maybe the app doesn't like Windows 10.
So if I could a sample of the TIMESTAMP.TXT file, I could change the info manually.
Phade, next time you run the TIMESTAMP.EXE app on the SD card, make a copy of the file and save it elsewhere. When you go to the field, estimate the date and time in the .TXT and place the saved file on your 2nd SD card. You won't have to play games running the app, just edit the file.
Best,
Jim
