• SNTP Broadcast Client – Configures the switch to operate as an SNTP broadcast
client. This mode requires no other configuration settings; the switch will obtain
time updates from time server broadcasts (using the multicast address 224.0.1.1).
• SNTP Poll Interval – Sets the interval between sending requests for a time update
from a time server when set to SNTP Client mode. (Range: 16-16284 seconds;
Default: 16 seconds)
• SNTP Server – In unicast mode, sets the IP address for up to three time servers.
The switch attempts to update the time from the first server, if this fails it attempts
an update from the next server in the sequence.
Web – Select SNTP, SNTP Configuration. Modify any of the required parameters,
and click Apply.

Setting the Time Zone
SNTP uses Coordinated Universal Time (or UTC, formerly Greenwich Mean Time,
or GMT) based on the time at the Earth’s prime meridian, zero degrees longitude. To
display a time corresponding to your local time, you must indicate the number of
hours and minutes your time zone is east (before) or west (after) of UTC.

• Hours (0-12) – The number of hours before/after UTC.
• Minutes (0-59) – The number of minutes before/after UTC.
