It seems that the print builtin doesn't take into account a change
of the environment with a parameter assignment. For instance:

cventin% zsh -c 'TZ=UTC print -P "%D{%c}"'
2019-04-10T14:53:50 CEST
cventin% zsh -c 'export TZ=UTC; print -P "%D{%c}"'
2019-04-10T12:53:53 UTC

Is there any (undocumented?) reason or is this a bug?

I'm using zsh 5.7.1 under Debian unstable.
