I see there have been several non-LWP suggestions, and unfortunately this is
another. But, what you describe sounds extremely similar to what Nagios and
its checks do so I'll just mention that I use the as-shipped check_http module
to do that as follows:
define command {
command_name check_https_cert
command_line $USER1$/check_http -S -C 30 -H $HOSTADDRESS$ $ARG1$
$ARG2$ $ARG3$
}
And then in a service definition I use one of (obviously altering the
www.example.com to the hostname of the virtual server I'm interested in if a
host serves for multiple names):
check_command check_https_cert
check_command check_https_cert!-H!www.example.com
Sorry it's not a pure perl solution, but it does address your ultimate need
even though it's not exactly how you were asking for it to be done.
You can find it as part of the normal plugin package at:

or your favorite OS package manager.
