We'll simply need to store the next moment when the DST correction

expensive operations.
This seems to be what libc does (from looking at an strace of some gcc
binary).
Correct (I had checked as well), but the only purpose that serves
is to check whether the system timezone info has changed.
This is something that normally doesn't happen unless you move your
system from one timezone to another or during system setup, so I
question the desirability of this check.
