Description (partial)

Symptoms: Clock synchronization with the NTP server could be lost for several
hours if router (NTP client) runs NTPv4.

Conditions: The symptom is observed if the router clock is reset (for example:
by using the <CmdBold>clock set<noCmdBold> exec command). The router then takes
a long time to synchronize again.
