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

It's probably not part of any standard or anything like that, but you could always use a Unix timestamp as those only contain digits. See this article for ways to convert it to a .NET DateTime.

Answer 2

Yes. ISO 8601

Just make sure you URLEncode it to deal with the colons.
