My camera produces files like
MVI_1234.AVI with timestamps on those files. Unfortunately the time wasn't set properly and timestamps are off.
I would like to set the file's timestamp on disk. (not the EXIF data).
1 read file's modify date 2 add delta, i.e. hhmmss (preferred: change timezone) 3 write new timestamp
Is there an easy way to do this? maybe one could simplify the calculation using epoch time (seconds since) and whip up a shell script.
