Not anymore, since Ralf Wildenhues fixed it two years ago (2010-08-21)
with commit v1.11-188-gb268a1f "Improve robustness of mdate-sh script":
Improve robustness of mdate-sh script.
* lib/mdate-sh: Sanitize zsh behavior on startup, to ensure
$ls_command is word-split properly upon invocation.
(error): New function.
(main): Use it. Improve error checking to avoid endless loop
in case $ls_command gave bogus output. Fix eval quotation.
* tests/mdate6.test: New test, to expose eval quotation error.
* tests/Makefile.am: Update.
The script will still experience an error, though (which is better
than an endless loop).

What happens if TIME_STYLE is simply unset?
