Change all dates to NOW

[marciano]

The camera was without battery for a while so all dates are 2012...
How to change them all to present date/time?

[StarGeek]

Try
exiftool -AllDates=now /path/to/files/

Great! Thank you!
Only warnings like this but didn't affect the result.
Warning: [minor] Maker notes could not be parsed

That means that for whatever reason, exiftool couldn't read the data in the maker notes.  It really won't affect the image or other data in the file.  See the end of FAQ #15.
