There's a proverb for this:
Give a man a fish and you feed him for a day; teach a man to fish and you feed him for a lifetime.

    Or maybe:

    Give a man a fish and he owes you one fish.

    Teach a man to fish and you lose your monopoly.

    Fortunately that's not how PerlMonks generally works though. ;)

    The way I learned it:
    Give a man a fish and you feed him for a day;
    Teach a man to fish and he'll spend his life savings on fishing tackle.
    But seriously, in this one man's opinion, there is more grace available here at PM for those in need of a clue than there is in most places on the web. You are required to take advantage of it by reading the links, but it's generally worth the result. Which leads to the equivalent:
    Give a man a Perlish App, and he'll have a solution for the problem at hand;
    Teach a man to use PM, and he'll spend the rest of his life perusing the Monastery (and CPAN).

[stevieb]: atcroft: "Make both hands into fists..."... is something my Ma taught me in our native lang, but I was to ignorant and young to pay attention. Thanks for that :)
[atcroft]: stevieb: Sad to say that I only recently learned that particular trick, but I have since found it very useful.... :)
[james28909]: ill be back with a solution eventually
[stevieb]: it's a reminder to re-inforce it :P
[atcroft]: james28909: That particular questions was a bit of trick, actually (depending on the country you are in). More interesting is, if you are trying to subtract from an epoch time, for instance, you might have to consider when/if DST occurs for a location,
[atcroft]: because you may have to adjust the number of seconds you change from an epoch from 86400 (not to mention leap seconds)....
[atcroft]: james28909: Although if your program is using a database, you might be able to "pass the buck" to the database and ask it to do the date change for you....
