Since our 9.2 upgrade, we've had a number of users that post the incorrect date format (DD/MM/YY instead of MM/DD/YY) when posting comments on defects.

I'm aware that the date in this case comes from the local machine, but looking at control panel/regional settings, the date format is correct. It also only happens with the users windows profile. If another user logs into the machine, it doesn't happen. We also tried changing the date format a couple times in control panel, to see if it'd overwrite it, it doesn't.

HP's "solution" was to totally delete the users windows profile and reset to defaults, which - even after I spend quite a while restoring most of it - runs the risk of breaking his other applications. They appear to have no idea where specifically QC gets the date format from.

Any ideas?
