System Time
The gateway uses the Simple Network Time Protocol (SNTP) to set its internal clock
based on periodic updates from a time server. Maintaining an accurate time on the
device enables the system log to record meaningful dates and times for event
entries.
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 select your time zone.
Figure 4-10 System Time
Time Protocol – Select SNTP to enable the unit to set its internal clock based on
periodic updates from a time server. The unit acts as an SNTP client, periodically
sending time synchronization requests to a specified time server. Alternatively, you
can select “None” and set the time and date manually. (Default: SNTP)
Time Server Address – The IP address of a time server that the unit attempts to
poll for a time update. (Default: 192.43.244.18)
Current Time (hh:mm:ss) – Displays the current time of the system clock.
New TIme (hh:mm:ss) – Sets the system clock to the time specified.
Current Date (yyyy:mm:dd) – Displays the current date of the system clock.
New Date (yyyy:mm:dd) – Sets the system clock to the date specified.
Set 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
select your time zone from the pull-down list. (Default: (GMT+08:00) Taipei)
