    ISO8601 is the best format and the international standard to denote date and time.

      I’m not sure I would agree with that. ISO-8601 is ambiguous, and very difficult to parse. For example, here are a couple valid ISO-8601 strings. Could you let me know what they mean?

      P1DT1H
R10/2021-208/P1Y
T22.3+0800
22,3
2021-W30-2
2021-W30-2T22+08
P1Y
20

      Taken from here. My favorite is the last one (20). If someone just wrote 20 and told you to parse it using ISO-8601, what would you get? Hour? It could even be century (ie. 2023%100)!!

      So I would argue that ISO-8601 is just a wee bit too flexible. Personally, I like RFC 3339 just a bit more…

      Edit: that said, I would definitely agree that something along the lines of 2021-07-27T14:20:32Z is better than any regularly accepted alternative, and I pretty much format my dates that way all the time.

        1. A period of one day and one hour.
        2. A period of one year, ten times, from the 208th day of 2021.
        3. Ten hours and 18 minutes pm (I’m not sure about this one) on UTC+08:00 (China, for example).
        4. IDK.
        5. The 2nd day of the 30th week of 2021.
        6. Same as above, but at 22:00 in China, probably.
        7. A period of one year.
        8. IDK.
