FIELD
DESCRIPTION
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).
Use Time Server
