This object is used to control whether the device uses the Simple Network Time Protocol (SNTP), to synchronize the device's clock to the Coordinated Universal Time (UTC). If the value is disabled(1), the device will not synchronize it's clock using SNTP. If the value is unicast(2), the device will first synchronize shortly after boot time when network access becomes available, and periodically thereafter, as specified by the value of s5AgSntpSyncInterval. If the value is not unicast(2) at boot, the device will synchronize when the value is first set to unicast(2), and periodically thereafter. Synchronization process: This process applies to automatic (periodic) and manual synchronization attempts. The device will first attempt to synchronize with the primary NTP server as defined by s5AgSntpPrimaryServerAddress (if non-zero). If the primary server synchonization is attempted and fails, the s5AgSntpPrimaryServerSyncFailures counter is incremented. The device will then attempt to synchronize with the secondary NTP server as defined by s5AgSntpSecondaryServerAddress (if non-zero). If the secondary server synchronization is attempted and fails, the s5AgSntpSecondaryServerSyncFailures counter is incremented. If synchronization succeeds with either server, the s5AgSntpLastSyncTime and s5AgSntpLastSyncSource values are updated. The s5AgSntpNextSyncTime value is updated on success or failure. For the special case of first sync failures, the system will automatically retry every few minutes until synchronization is achieved without regard to s5AgSntpSyncInterval.
