Time and Log

Simple Network Time Protocol (SNTP) allows the access point to set its internal 
clock based on periodic updates from a time server (SNTP or NTP). Maintaining an 
accurate time on the access point enables all system log messages to be stamped 
with the correct time and date. If the clock is not set, the access point only records 
the time from the factory default set at the last bootup.

The access point acts as an SNTP client, which periodically sends time 
synchronization requests to a specific time server. 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 the time 
corresponding to your local time, you must also indicate the number of hours your 
time zone is located before or after UTC/GMT.

Figure 4-15.   SNTP Settings

The displayed items on this page can be described as follows:

SNTP Server

 Setting — Configures the access point to operate as an SNTP client. 

When enabled, the time server IP address must be specified.

Primary Server

: The IP address of an SNTP or NTP time server that the access 

point attempts to poll for a time update. 

Time Zone

 — Sets the number of hours your local time zone is located before or 

after UTC/GMT. (Default: GMT+00)

Daylight Saving

 — The access point provides a way to automatically adjust the 

system clock for Daylight Savings Time changes. To use this feature you must 
define the month and date to begin and to end the change from standard time. 
During this period the system clock is set back by one hour.
