Netgear M4300-28G (GSM4328S) - Stackable Managed Switch with 24x1G and 4x10G including 2x10GBASE-T and 2xSFP+ Layer 3 Administrator's Guide

After configuring the IP address, enable SNTP client mode. 

The client mode can be either broadcast mode or unicast mode. If the NTP server is not 
your own, you must use unicast mode.

When the SNTP client mode is enabled, the client waits for the polling interval to send the 
query to the server. The default value is approximately 1 minute. 

After this period, issue the show command to confirm that the time was received.

The time will be used in all logging messages.
