Petty complaint:
ISO 8601 is the only date format that doesn’t force the reader to guess.
Look at these three strings:
17/09/25 14:00
25/09/17 2:00
09/17/25 14:00
Without context you can’t tell which number is the year, the month, or the day; every interpretation is equally plausible, so every reader loses.
2025-09-17 14:00,
Boooom, Instantly unambiguous: left-to-right you get year, month, day, hour, minute. It also sorts correctly as plain text.
Please, use ISO 8601 everywhere, anything else just wastes time and confuses people.
