A function called strftime is what you're after. It's in the POSIX and Date::Format CPAN modules

I want to compare the date which i get read from the xml file with today's date and if it is greater than 60 days then need to do a action else other action.

Please share ur views with me,

Thanks in advance

This below prog is to calculate the diff of days.
I hardcoded most. if you want to use dd-mm-yy format you can use split function for date arrays.

#!/usr/bin/perl
                    # perl binary

@std_date=(1,1,1800); # cal starts from this year

@date_one=(21,06,2006); # first date
@date_two=(20,06,2007); # second date

@days_of_month=(31,28,31,30,31,30,31,31,30,31,30,3 1);

$count1=no_day(@std_date,@date_one); # date_one - std_date
$count2=no_day(@std_date,@date_two); # date_two - std_date
$count=($count1 > $count2) ? $count1 - $count2 : $count2 - $count1;
                    # date1 - date2

print "\n\tNo of days : $count\n\n";

sub no_day
    {
    @std=($_[0],$_[1],$_[2]);
    @date=($_[3],$_[4],$_[5]);
    $count=0;

    #adding the days for year
    for($i=$std[2];$i<$date[2];$i++)
        {
        $count+=365 if(leapyear($i));
        $count+=366 if(!(leapyear($i)));
        }

    #adding the days for month
    for($i=@std[1];$i<$date[1];$i++)
        {
        $count+=$days_of_month[$i-1];
        }

    #adding the days and return
    return($count+=$date[0]);

    }

sub leapyear # is it leap year
    {
    $in=$_[0];
    if(!($in%4))
        {
        if($in%100)
            {
            return(0); # if leap year
            }
        else
            {
            if(!($in%400))
                {
                return(0);
                }
            return(1)
            }
        }
    return(1); # if it is not leap year
    }
