Yes, for instance, I would have assumed the following to be similar:
cventin% zsh -c 'TZ=UTC print -P "%D{%c}"'
2019-04-11T12:41:37 CEST
cventin% zsh -c 'p() { print -P "%D{%c}" } ; TZ=UTC p'
2019-04-11T10:41:41 UTC
I don't see any reason why the current execution environment would
have a different meaning in the first case.
