add non-ambiguous ISO-ordered date/time formatting
I'd like to see a non-ambiguous date/time format added to Redmine, which also respects standard ISO ordering.
ISO ordering is largest --> smallest component. In practice, that means year > month > day > hour > minute > second.
Non-ambiguous means that some indicator must be present to show what component is the day-of-month and what is the month-of-year.
I've attached a patch that fixes this in the easiest and most readily legible way possible for all nationalities.

@Felix: %Y-%m-%d is not a good enough format, since it is ambiguous for any dates where the day-of-month is 12 or less.
There is no way of telling from reading such a printed date, eg. 2011-01-12, if it is (in this example) january 12 or december 1.
