Query in Perl Programming

[S, Rajini (STSD)]

Hi, 

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

In perl is there any system defined functions to find out the Differences in 
dates. 

Eg : 

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

So the difference between two dates is 12 days. 

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