SNMPv3 error Perl Net::SNMP - Time synchronization failed during discovery - Powerware ConnectUPS-MS with firmware version HF

SNMPv3 error Perl Net::SNMP - Time synchronization failed during discovery - Powerware ConnectUPS-MS with firmware version HF
The Net::SNMP module uses the procedure outline in Section 4 of RFC 3414 to perform discovery.
It seems that the Eaton Powerware ConnectUPS-MS NIC running version HF firmware does not enforce timeliness checking and is not responding with a usmStatsNotInTimeWindows Report-PDU during the discovery process.
You can work around this by editing the lib/Net/SNMP.pm and removing the '($this->{_error} =~ /usmStatsNotInTimeWindows/)' part of the if statement.
