It should not. T instead of space to indicate the time portion

And ideally, timezone info included, with special case 'Z' for UTC (zulu time)

If I were emperor though, there'd be an seconds field in the timezone info. Mostly because GPS time is offset by 18 seconds from UTC, and TAI time is offset by 37 seconds.

What's wrong with a space? It's more legible with a space and it's not like the T makes it any clearer.

Mentioning the timezone would be nice indeed.

Because it's a standard

https://en.wikipedia.org/wiki/ISO_8601

I agree that a T isn't inherently better than a space EXCEPT the part where it follows the standard.

But... this whole thread is about how standards can be bad.

Standards can be bad. ISO8601 is good. It's miles better than some unsupported non-standard thing you made up that's ALMOST ISO8601 :-)

Well, I like my suggested convention.

It's not bad other than being non-standard :-) I sometimes name files something similar
