Is there a standard date/time format that can be passed on a URL?

Question

Looking at the DateTimeFormatInfo documentation, it appears that all the standard formats have colons in them, which makes passing them on a url unpleasant/impossible.

Answer 1

We actually have a reporting solution where dates and times can be passed in as plain text CCYYMMDD and hhmmss values then, when the code needs to do anything to those values, it simply uses string operations to turn them back into a format that can be displayed or easily parsed (such as the DB2 ISO formats CCYY-MM-DD or hh.mm.ss).

The result is readable and I'd be surprised if .NET didn't have string manipulation instructions that could do this easily.
