change it to the more generic description
"please run this job whenever local time shifts due to tz data"
and you've got something. think "local sidereal time".

sounds sorta like the @reboot pseudo-time, which doesn't get executed
because you rebooted the machine, but because you "rebooted" (or
restarted) cron itself.
keep in mind that you'll also have to keep local state in as atomic a
fashion as possible, since you can't guarantee that the machine will
be running when time shifts.
