Keeping the original time-date stamp of video files

[ffrree]

I use the command line syntax

exiftool -rotation=90 file.mp4

to rotate a file.

Is there a way I can keep the original time date stamps ( eg. creation date, modified date ) etc., these are important as I use them to sort the time sequence of my video files.

Add the -P (preserve) option.

Thanks StarGeek.  Works like a charm, just have to ensure I used -P not -p ( case-sensitive )....haha.   Forgotten all my Unix syntax sensibilities. haha.  Back to the good old UNIX days of 30 years ago.
