date conversion in perl -

-

i using perl access db getting date in dd-mon-yyyy format. need perform 2 operations:

  1. convert format mm/dd/yyyy format.

  2. compare date 2 dates see if lies in time range.

    my $chdate = '15-feb-2013';

    sub get_stats {

    my %map = ( 'jan' => '01', 'feb' => '02', 'mar' => '03', 'apr' => '04',             'may' => '05', 'jun' => '06', 'jul' => '07', 'aug' => '08',             'sep' => '09', 'oct' => '10', 'nov' => '11', 'dec' => '12');      $chdate =~ s/(..)-(...)-(....)/$map{$2}\/$1\/$3/;     print "new date: $chdate";

    }

how perform (2) operation?

i have old version of perl (no time::piece module), not have privileges update :)

for (2) can this:

sub dateasnumber # arg mm/dd/yyyy - converts number compared {    $_[0]=~m%(\d\d)/(\d\d)/(\d\d\d\d)%;    return (($3 * 400 + $1) * 40 + $2); }  $test = &dateasnumber($testdateasstring);  if (&dateasnumber($startdateasstring) < $test &&     &dateasnumber($enddateasstring) > $test) {    print "$test date between $startdateasstring , $enddateasstring\n"; } else {    print "$test date not between $startdateasstring , $enddateasstring\n"; }

i have been playing around irb , have string looks this: irb(main):072:0> puts ["[\"4354 5432 5432 xxxxx\", \"6547 6547 8543 xxxxx\", \"2344 6543 6674 xxxxx\", \"2346 6236 7543 xxxxx\", \"1273 5585 5587 xxxxx\"]"] => nil irb(main):073:0> what want gsub last 2 "x" s of each 17 digit combination, 23 . what i've tried far (i've been using rubular): a.gsub(/\d[x]/,"23") <= grabs "x" s i'm close a.gsub(/\w[x{2}]/,"23") <= grabs "x" s grabs two digits each combination. is there easier way i'm not understanding? a.gsub(/\d{4} \d{4} \d{4} xxx\kxx/, '23') \d{4} = 4 digits what \k drop matched far. can use don't replace entire number, still able validate have in desired format.
