    Well it depends. Your date looks like a Unix print-out format. If you obtained this date with the time Perl function, then this function really returns a number, i.e. the number of seconds elapsed since the epoch (1-Jan-1970 on Unix systems). This number can be converted into an array containong the various element of the date with the gmtime and localtime functions. This array contains:
    - 0 : seconds
    - 1 : minutes
    - 2 : hours
    - 3 : day in month
    - 4 : month (Jan = 0, Feb = 1, etc.)
    - 5 : years elapsed sin 1900,
    - 6 : day of week (0 = Sunday)

    The Time::localtime module makes it possible to access these elements by name, if you prefer.

    But if you have the string "Tue Feb 11 08:47:59 2014", then you probably have to use regexes to reformat your date to your target format (although there may possibly be a module doing it, I don't know).

    Try using Date::Parse perhaps.

    my %month;
    @month{qw(Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec)}=(1..12);
    my $date="Tue Feb 11 08:47:59 2014";
    $date=~s{^([a-zA-z]{3}) ([a-zA-z]{3}) (\d\d) (\d\d:\d\d:\d\d) (\d\d\d\d)$}{$5-$month{$2}-$3 $4};

    That's about the worst you can do. It's the fast way to make a very bad coder out of you. It's important to understand what you are doing. Just asking what you should do, and blindly copying that if you would have gotten an unambigious answer is very, very bad.

    Use the POSIX module and in particular the strftime routine.
