You cannot reset the timezone in a running process without a bit of
hackery in the source.
(It might be possible to use ptrace()/gdb to do it somehow, but I'm
not familiar with how, and it's certainly ugly.)
If you reset the clock time, crond should pick up the new time, sleep
a while if it went backwards, and continue.
