LABEL DESCRIPTION
Time Protocol 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 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 None to enter the time and date manually.
