All the parts of the standard that discuss Universal Time or time zones specify that everything is based on Coordinated Universal Time (UTC). But UTC didn't...
8601 also requires the use of the Gregorian calendar, which did not exist prior to 1582, for all dates. It is easy to extrapolate back. For time, the concept...
Some people who write in Wikipedia are interested in using microformats to provide a machine-readable version of important dates and times, in the hopes that...
In a very strict technical sense it may have been overlooked. However, prior to atomic clocks, you have to relax the formality of beating in synch with atomic...
Did the responses answer your question sufficiently? The problem(s) are not really with the standard. As you go back in time, UTC doesn't exist, time zones...
Right. Doesn't the standard call for a proleptic Gregorian calender for dates before 1582 & after the present (and that more digits/negative dates are allowed...
... Yes, but seconds generally aren't important in day-to-day events anyway. If you're going to try to calculate an offset to great precision you may need to...
I was thinking of historical examples like the offset The Netherlands used sometime in the last 100 years that had an offset precise to the centisecond....
I started this thread. After seeing the responses, I don't really see anything that would change my ideas, but knowing that my thoughts have been reviewed by...
Hi, You are welcome to do whatever you want of course, but I don’t think this is what was suggested or recommended and I don’t think you should in any way ...
I agree with Tex's remarks. But I would add the following three points: *Dates don't have time zones. Only times or "date and time" representations have time...
John Good comments. I am surprised by your comment on dates. Dates definitely do have time zones. Since time zones span 25 hours, without mention of the zone, ...
... That's fine if your application imposes such restrictions, but it is not what ISO 8601 requires. ISO 8601 fixes some notations but it does not constrain...
... True, so we may never know the offset, but that doesn't interfere with using ISO 8601. You can simply indicate "local time" by not specifying the offset....
Tex,  I agree with the dilemma you pose. In reality, that means date alone often does not suffice and you must consider time of day as well.  However, in...
When I mentioned in an earlier post that I would reject certain date-times in the ISO 8601 format, I meant that I would halt processing or flag them for...
