Table 11-3 Time and Date Setting Fields

Enter 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 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.
NTP (RFC-1305) is similar to Time (RFC-868).
None is the default value. Enter the time manually. Each time you turn on the
ZyWALL, the time and date will be reset to 2000-1-1 0:0:0.
Enter the IP address of your time server. Check with your ISP/network
administrator if you are unsure of this information.
