nivrip, I think that there's a mixture of both mm/dd/yyyy and your own computers setting dates spread throughout the site (i.e., in your case dd/mm/yyyy). Personally, I think it'd be far better to either have them ALL determined by your own computer settings OR to have the month spelt out - i.e., Jan, Feb, Mar etc.

I am afraid that somebody has played with the language_country setting routines.

WCG web pages use an "&language" parameter to format dates and numbers, and formerly this parameter was set correctly when you used the "Select Language" command.
For example for me it was set to fr_FR and for a user in Quebec it was set to fr_CA.

Currently (I have just checked) this setting is America-oriented, i.e. -
- if I select English &language is set to en_US
- French -> fr_CA
- Spanish -> es_MX
- Portuguese -> pt_BR.

As far as I remember, in the past, after setting the correct value (e.g. fr_FR for me) it was kept for all pages but a few, while now each page reset it to the wrong value (probably a systematic call to the badly coded language routine).

What is worse in your case is that even trying en_UK (or en_EN, I don't remember the correct values) dates are still displayed in that silly US format.
Which forbids you to benefit from my personal trick : I have added &language=fr_FR in all my saved calls to statistical pages, and (crossed fingers) it is still working fine.

Edit: nivrip, I tried en_CA to see if it could please you. At first it looked like being a possible temporary bypass for you. Unfortunately in every page I have tried there is a mixture of normal and US date formats!!!
