This read-create Integer32 (0-360 seconds) sets a minimum value for a DHCP request's 'time elapsed' field before the relay agent will forward it, used to prioritize clients that have already been waiting. An admin raises this to make the relay agent hold back forwarding brand-new requests briefly, giving priority to clients that have retried longer, useful in DHCP failover scenarios. For example, setting this threshold above zero means a client's very first DHCP discover attempt might not be immediately relayed, only its subsequent retry once it has been waiting long enough.
