Counts ICMP Timestamp, or request, messages sent by the device, asking a peer for its clock value. As with the inbound timestamp counters, this outbound request type is rarely used in normal Check Point operation, so a nonzero value likely traces back to a specific diagnostic tool or script run from the gateway rather than routine traffic. Example: finding icmpOutTimestamps incrementing right when a network engineer was running an old-school clock-skew diagnostic from the gateway's CLI accounts for the otherwise unusual traffic.
