Time Protocol Select the time service protocol that your time server uses. 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).
Time Server
Address
Enter the IP address or URL (up to 20 extended ASCII characters in length) of
your time server. Check with your ISP/network administrator if you are unsure of
this information.
Time Zone Setup
Time Zone Choose the time zone of your location. This will set the time difference between
your time zone and Greenwich Mean Time (GMT).
Enable Daylight
Savings
Daylight saving 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 daytime light in
the evening.
Select this option if you use Daylight Saving Time.
