I'd look for someone who's solved the problem before and use their solution. In this case, DateTime
, and/or Date::Manip
are all excellent solutions to this problem (and the general problem of dates and times).
In most other situations, you will realize you're solving a problem others have already solved. In the other cases, use a dispatch table or a trinary.
Being right, does not endow the right to be rude; politeness costs nothing.
Being unknowing, is not the same as being stupid.
Expressing a contrary opinion, whether to the individual or the group, is more often a sign of deeper thought than of cantankerous belligerence.
Do not mistake your goals as the only goals; your opinion as the only opinion; your confidence as correctness. Saying you know better is not the same as explaining you know better.
