There are many modules on CPAN for manipulating dates and times; you
could convert the parsed time value into a standard time format, then
subtract that.
But it may be easiest for you if you break your four-digit string into
hours and minutes and do the math that way. You may be able to use the
% (modulus) operator to help:
my $diff = ($my_hour - $their_hour) % 24;
Good luck with it!
