Hi there,
I'd like to report a bug i found. If you try to insert date and time in the last example you find here: http://www.asp.net/ajaxLibrary/AjaxControlToolkitSampleSite/MaskedEdit/MaskedEdit.aspx
you can see that as soon as the box loses the focus, the time changes and gets the same value of month and day.
Example:
I write 22/12/2012 18:30
it becomes 22/12/2012 22:12
it worked fine with the previous releases.
