:: Note: The '1's in this line are to convert a value like "08" to "108", since numbers which
::       begin with '0' are interpreted as octal, which makes "08" and "09" invalid. Adding the
::       '1's effectively adds 100 to both sides of the subtraction, avoiding this issue.
::       Hours has a leading space instead of 0, so the '1's trick isn't used on that one.
