LABEL DESCRIPTION
Use Time Server
when Bootup Select the time service protocol that your time server sends when you turn on the
ZyWALL. Not all time servers 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 difference between them is 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 None to enter the time and date manually.
Time Server IP
Address Enter the IP address of your time server. Check with your ISP/network administrator
if you are unsure of this information (the default is tick.stdtime.gov.tw).

Each time you reload this page, the ZyWALL synchronizes the time with the time

Daylight Savings.
