Dates of some audio recordings are missing or incorrect

[jiru]

The date audio recordings have been added or modified is now displayed (#2275). Due to previous implementations, some of these dates need fixing, for example:

• https://tatoeba.org/sentences/show/1140975 Added date unknown
• https://tatoeba.org/sentences/show/373460 Added January 1, 1900; Last modified August 13, 2022

There are 3 sentences with audio added date on January 1, 1900: 373460, 379998 and 2504981.

There are 334549 audios with added date unknown. Maybe CK’s lists could be used to restore the date manually in some cases. @ckjpn Apart from what’s visible in theses lists, do you have any historical data that could help?

If dates on the files haven't been changed since uploading, you can likely use those dates.
When I first started putting all the audio files sorted by voice into lists, that's how I was able to easily group large numbers of files as being by a given voice.

Note that the date at the end of the titles for audio lists is the date that member started contributing audio files.
In some cases, it's the only time a member. contributed audio files.
