Log filenames can be confusing

[fflorent]

From @shukon in #116 (comment):

I wondered why you would use 220114 as a timestamp in the archive-names instead of 2022-01-14 or at least 2022014. It's an ISO-norm that makes a lot of sense imho. There are a lot of possible interpretations for e.g. 071211 ;)

I tend to agree, if someone look at this filename:
250824_0000.log

Does it mean?

• 2025-08-24 (yes!)
• 2024-08-25 (nop)
• 2024-25-08 (WTF, but that would be the traditional American date format)

Also it would be consistent with the yunohost operations logs stored in /var/log/yunohost/operations/ to use this format:

date +"%Y%m%d-%H%M%S"`

Any thoughts?

FWIW, if someone looks into these logs, I'd suggest to check at the same time if some sort of purging of the oldest of these files would be interesting, along those lines: #158 (comment)
