No, I think system settings should be used if possible - and I’m pretty sure they’re coded to do so. Unfortunately, my system is mon-day-year so it all looks right to me.
Most likely one of these is in play:
- there’s a Duplicati bug in how the dates are displayed
- there’s a bug in how mono is reporting the dates to Duplicati
- the date settings you’ve set as dd/MM/yyyy aren’t the ones used by mono or Duplicati
For example, on Windows I can change the date format of the clock - but that won’t change the system stuff. However if I change my machine location, then the date formats DO change.
