This read-write integer (1-65534) sets, in seconds, how long the time client waits for a UDP response from the time server before considering the request timed out. An admin adjusts this based on network latency to the time server to avoid premature timeouts or excessively long waits on a failed request. For example, on a high-latency WAN link to the time server, an admin might raise timepClientUdpTimeout above its default to avoid spurious retransmissions.
