The extended date format, as Evan has written it, is great and I love using it as often as possible.
I feel compelled though to mention this is not a way to "handle time" - for that the combined date and time format is needed, e.g.
2026-11-01T08:18:00Z or 2026-11-01T18:48:00+10:30 😉
The full standard when it comes to date and time is a bit unwieldy for daily use and like most people I'd use an unofficial modification -- omit the "T" divider and the timezone, and perhaps even the seconds in the time: 2026-11-01 08:18
ISO-8901, generally speaking, is great and I'd like to see it adopted even more widely.
There's some funny examples of people messing it up on Reddit: https://www.reddit.com/r/ISO8601Today is 2026-11-01. ISO-8901. Is it is the only way to handle time?
