Re: set temporary environment variables for builtins

Thanks.  That worked.

Still wondering why the standard syntax for setting a temporary 
environment variable doesn't work for builtins.

I don't think I'm unusual in expecting this to work:

TZ=Europe/Paris print -P '%D{%z}'

Granted this is much more likely something someone would use with TZ=UTC.
