in thread Logical ways to calculate being within two times

To guard against the infinite loop / leapsecond / 59 second minute

my $failsafe = 0; $time += 60 until localtime($time) =~ /$on_at:/ or $failsafe++ > +10_000;

Adjust the failsafe cutoff until its just large enough but not too large :) If it slows down this approach change it :) maybe use strptime

    That breaks the loop, but doesn't fix up the problem.

    Adding 30 instead of 60 prevents the problem completely and runs more quickly.

    In the absence of evidence, opinion is indistinguishable from prejudice.

      Just came across this article this morning. Google is, instead of doing the leap second, is going to slow their clocks on their NTP servers by 0.0014% over the 10 hours before and 10 hours after the leap second.

      Also, they've opened up these servers to the public.

      ps. I changed my code with the 30 second modification.
