Changes the access and modification times on each file of a list of files. The first two elements of the list must be the NUMERIC access and modification times, in that order.

#!/usr/bin/perl
$atime = $mtime = time;
utime $atime, $mtime, @ARGV;

Since Perl 5.8.0, if the first two elements of the list are undef, the utime(2) syscall from your C library is called with a null second argument- On most systems, this will set the file's access and modification times to the current time (i-e-, equivalent to the example above) an
