Incorrect uptime of Security Gateway object in SmartConsole.
NTP server is configured correctly.
Snmpwalk command return the correct value.
After 'cpstop; cpstart' the issue is resolved, but after a machine reboot the issue replicates and the value of 'stattest' command (stattest get 188.8.131.52.4.1.26184.108.40.206 ) return a wrong value.
When SNMPD is re-started, the uptime value which was saved when the system was started is over-written.
