The more commonly-used ISO format is the extended format rather than the
basic one:
YYYY-MM-DDTHH:MM:SS+ZZZZ
(and yes, the T is part of the format). More commonly, people use the ISO
extended date format and the ISO extended time format separately with a
space between them and the time zone also separated out:
YYYY-MM-DD HH:MM:SS +ZZZZ

I agree. The ISO format is better if you need to write out a date to a
file that you're reading later and you don't need absolutely maximum
speed, particularly if you have good tools to parse it and turn it back
into a native format again.
