I have the oid to get system time from linux, but is it possible to determine the system timezone via snmp on a redhat/centos box?

What format is the raw time data coming in? Sometimes the time zone is embedded (e.g. date command). – JeffG Mar 24 '11 at 13:07

The hrSystemDate.0 object returns the local timezone:

HOST-RESOURCES-MIB::hrSystemDate.0 = STRING: 2011-3-24,6:20:24.0,-6:0
                                                                 ^^^^

The suffix shows the time offset from GMT.

That looks good, is that setting it though? Or retrieving the value? I need to retrieve the value from the host. – Chris Mar 24 '11 at 13:38
That was done with snmpget (retrieving it). – Wes Hardaker Mar 24 '11 at 13:49
thanks, looks like the oid for hrSystemDate is 1.3.6.1.2.1.25.6.3.1.5.1? That returns a hex string. When I use snmpwalk with the above text query it doesn't recognize HOST-RESOURCES-MIB::hrSystemDate.0 ... – Chris Mar 24 '11 at 15:11
Then you need to set the MIBS to load properly if that's the case. Try snmpwalk HOST-RESOURCES-MIB::hrSystemDate and it should format it properly. The contents of the string is a series of numbers that represents the above text. See the DateAndTime textual convention in the SNMPv2-TC.txt MIB file that should be on your system. – Wes Hardaker Mar 24 '11 at 15:57

For those on ubuntu 10.10 x86_64, default install, where ubuntu is the polling host (where you're querying FROM), need the following mibs in /usr/share/mibs/netsnmp/ - IANAifType-MIB, SNMPv2-MIB, SNMPv2-SMI, SNMPv2-TC,HOST-RESOURCES-MIB. These fixed this issue for me at least. – Chris Mar 24 '11 at 16:16
