Describe the enhancement

I would like to be able to modify the way PrusaLink displays Time/Date information:

Current View, uses US date format (arguably the worst!):

I would like to be able to format this however I like (ideally with the same arguments as the linux date command, eg: %Y-%m-%d %H:%M:%S).

Expected functionality

All dates in PrusaLink/ (also in the xLCD ideally) follow the users preferred date/time format settings.

I live in the US and can confirm we have the worst date format. Please ISO. 🙏
