Why in Windows 7 do I see the Data & Time in DateTimePicker inverse and in Windows XP it is fine? (the region and language are the same)

For example:

Win7:  2010/12/31  -  51:09

XP  :  31/12/2010  -  09:51

Hello. You've been a member of StackOverflow for a year and have a high reputation score, so you're not exactly new here. What makes you think this is a programming related question? – Tamas Czinege Apr 16 '10 at 8:54
DataTimePicker, I guess. – mafu Apr 16 '10 at 8:56
Because Win7 has given you a sensible date format? (Unfortunately it has failed on the time :-(.) YYYY-MM-DD is the international standard format, and sorts textually with string comparisons. – Richard Apr 16 '10 at 9:55
I totally prefer the Y-M-D format, sure. I have no idea why time is reversed, are you saying it's the default? Makes no sense to me... – mafu Apr 16 '10 at 10:07
@Gold: You could probably avoid any confusion about this being programming related if you included the line of code that produces those results. – Bill the Lizard Apr 17 '10 at 1:59

You likely messed with the custom region settings. For instance, setting mm:hh instead of hh:mm for time display. The custom settings override the default regional settings.

The settings are used system-wide - in DataTime picker controls as well. If you want to use a certain, fixed format, you can simply set it on the picker.
