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. -- Vincent Lefèvre - Web: 100% accessible validated (X)HTML - Blog: Work: CR INRIA - computer arithmetic / AriC project (LIP, ENS-Lyon)
