in thread Trouble getting data out of a hash

First of all, the returned hash is empty so it's no wonder that you the uninitialzed warning. I've never used Net::SNMP but from a quick glance at the docs I see:
$result = $session->get_request( [-callback => sub {},] # non-bloc +king [-delay => $seconds,] # non-bloc +king [-contextengineid => $engine_id,] # v3 [-contextname => $name,] # v3 -varbindlist => \@oids, );
so I think you're call of request is wrong and should read
$result = $session->get_request( -varbindlist => [$OID] );

    Doing it that way got me an undefined data dump from result, and an error for uninitialized value when trying to print $result directly. Ithink there is something wrong with the hash reference being returned in $value, I'm just not sure how to fix it.

    Edit: I was right about the hash being incorrect, it seems I was grabbing the incorrect Object ID from the MIB. It needed as trailing 0 off of the the syscurrentDate object I was trying to take. Thanks for all your help in figuring this out.
