In principle you're right, but this seems to be something that people
ask for, with cron. And with the usual setup where scripts are stored
in /etc/cron.{daily,weekly,...} is was trivial to adjust the date globally,
by modyfing the crontab entry which runs those directories. When switching
to systemd units as they are defined currently this convenience is lost.

I think it is reasonable request. This feature is backwards compatible,
and requires user intervention to activate, so I'd say we can redefine
"daily" not to necessarilly mean "midnight".
