Logging: Use RFC/ISO date format
The date format on STDOUT/STDERR is strange 07/05/23 17:26:18
It would be great, if Gajim would adopt RFC/ISO date format with 2023-07-05 ...
https://www.rfc-editor.org/rfc/rfc3339 https://en.wikipedia.org/wiki/ISO_8601
Due to the RFC date format, the log entries would then also have continuous, growing timestamps.
Now we have 07/05/23 << 08/05/22 which makes no sense.
