How long is the NTP synchronization interval on an S series switch

The maximum NTP synchronization interval on an S series switch (except the S1700) is the tenth power of 2 in seconds, namely, 1024 seconds. The interval for clock synchronization between the NTP client and server is not fixed and depends on the clock precision. A higher clock precision results in a longer synchronization interval. The synchronization interval depends on the following two factors:
1. Time difference between the client and server
2. Frequency offset of the clock on the client compared with the clock on the server
