Here comes another useless addon that for whatever conservative reason is not included as part of Anki.

You will need this only when you run into this error:
<class 'ValueError'>: ZIP does not support timestamps before 1980

This addon auto updates the timestamp for the problematic media file(s), so you don't have to do it by hand.

Full details of this error are described here:

https://anki.tenderapp.com/discussions/ankidesktop/1305

https://anki.tenderapp.com/discussions/ankidesktop/35468

In using this addon, you agree to have the timestamp of any media file with a mod time of less than 1980 to be auto updated to the current time. A message will be shown after the timestamp update.
