Table 36-4 Menu 24.10 System Maintenance: Time and Date Setting

FIELD
Time Protocol Enter the time service protocol that your timeserver sends when you turn on the ZyWALL.
Not all timeservers support all protocols, so you may have to check with your ISP/network
administrator or use trial and error to find a protocol that works. The main differences
between them are the format.
Daytime (RFC 867) format is day/month/year/time zone of the server.
Time (RFC-868) format displays a 4-byte integer giving the total number of seconds since
1970/1/1 at 0:0:0.
The default, NTP (RFC-1305), is similar to Time (RFC-868).
Select Manual to enter the new time and new date manually.
Time Server Enter the IP address or domain name of your timeserver. Check with your ISP/network
Address administrator if you are unsure of this information. The default is tick.stdtime.gov.tw
Current Time This field displays an updated time only when you reenter this menu.
New Time Enter the new time in hour, minute and second format. This field is available when you
select Manual in the Time Protocol field.
Current Date This field displays an updated date only when you reenter this menu.
New Date Enter the new date in year, month and day format. This field is available when you select
Manual in the Time Protocol field.
Time Zone Press [SPACE BAR] and then [ENTER] to set the time difference between your time zone
and Greenwich Mean Time (GMT).
Daylight Saving Daylight Saving Time is a period from late spring to early fall when many countries set
their clocks ahead of normal local time by one hour to give more daylight time in the
evenings. If you use daylight savings time, then choose Yes.
Start Date Enter the month and day that your daylight-savings time starts on if you selected Yes in
the Daylight Saving field.
End Date Enter the month and day that your daylight-savings time ends on if you selected Yes in
the Daylight Saving field.
Once you have filled in this menu, press [ENTER] at the message "Press ENTER to Confirm or ESC to Cancel"
to save your configuration, or press [ESC] to cancel.
