cDhcpv4StatisticsResetTime 1.3.6.1.4.1.9.10.122.1.2.2

The time the server statistics counters were last reinitialized; the statistics counters are reinitialized by a reset command, server reload, or server start; note also that any configuration change to reporting interval requires a server reload to take effect, which will reinitialize the statistics counters. If statistics are never reset, this time will equal cDhcpv4SrvResetTime, which may also equal cDhcpv4SrvStartTime, if the server was never reloaded.
