Perl Find file age

Hi

I can not say that i am new to perl but today i learned something new, i wanted to know age (last time file got modified) of file so i initially thought of using find -mtime command but when i googled it, i found perl solution for the same

Code:
my $age = -M $ARGV[0] ; 

print "$ARGV[0] age is int($age)\n" ;

this gives when my file was last modified... can someone explain me what is this "-M" doing ??

I tried googling it but frankly i didnt know what to search for Smilie.

Also if you could give me link which explains this stuff then that will be more useful for me ..
