Check simply the time function. It returns the number of seconds since January 1, 1970.

For example:

Code:
$ perl -e "print time"
1344620607


This guaranteed to be unique each time you run your script (unless you run it several times per second).

You could use Data::UUID.

This will generate unique values even when running multiple times a second and guarantees unique values until 3400 AD.
