The W3C has a profile of ISO 8601 which simplifies life: http://www.w3.org/TR/NOTE-datetime Also IETF have a RFC "Date and Time on the Internet: Timestamps": http://www.faqs.org/rfcs/rfc3339.html Other Relevent standards that specify dates are: RFC 822 and RFC 1123 The HTTP protocol accepts dates in a number of formats, from section 3.3.1: "HTTP applications have historically allowed three different formats for the representation of date/time stamps: Sun, 06 Nov 1994 08:49:37 GMT ; RFC 822, updated by RFC 1123 Sunday, 06-Nov-94 08:49:37 GMT ; RFC 850, obsoleted by RFC 1036 Sun Nov 6 08:49:37 1994 ; ANSI C's asctime() format" Hope this helps Mark
Quoting [Christopher Smith] (May 05 2006):
Does anybody have a pointer to the relevant ISO standard?
Is there an ISO standard for that?
I found this link:
http://www.iso.org/iso/en/prods-services/popstds/datesandtime.html
but I haven't read it in any detail.
