Query in Perl Programming

Hi,=20

I am new to Perl Programming and have a query in perl.=20

In perl is there any system defined functions to find out the Differences i=
n dates.=20

Eg :=20

Date 1 -> 26-Jan-2009
Date 2 -> 14-Jan-2009=20

So the difference between two dates is 12 days.=20

Is there a way to achieve this with any system defined functions In Perl ??=
??
