A quick look at the snmp_monitor.tcl script show the following:

        set err [catch {$s get $uptime} vbl]
        if {$err || [snmp type $vbl 0] == "noSuchInstance"} {
            ined acknowledge "Time base problem on $ip: $vbl"
            $s destroy
            return ""

So the script first checks whether the time base variable
(SNMPv2-MIB!sysUpTime.0 in your case) is readable. The noResonse error
message means that the agent did not respond to the get request for
SNMPv2-MIB!sysUpTime.0. Check your configuration and make sure the
agent is able to respond to requests for SNMPv2-MIB!sysUpTime.0.
