Perl String Date Formating

[POB]

Having to use Perl for the first time to create example access to a webservice I have made in .Net.

If I have a string like this:

2009-11-19 21:01

I want to only display the time part in 12 hour format so it would become:

9:01 pm.

I'm being incrediably thick and can't work this out after googling.

Is there a function for formating strings directly?

Thanks works great!

Will be very glad to see the back of this Perl.
