Time and Log
Simple Network Time Protocol (SNTP) allows the NXA-WAP250G to set its internal clock based on
periodic updates from a time server (SNTP or NTP). Maintaining an accurate time on the NXA-
WAP250G enables all system log messages to be stamped with the correct time and date. If the clock is
not set, the NXA-WAP250G only records the time from the factory default set at the last bootup.
The NXA-WAP250G 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 (FIG. 29).
The displayed items on this page can be described as follows:
 SNTP Server Setting — Configures the NXA-WAP250G 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 NXA-WAP250G
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 NXA-WAP250G 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.
