Bootup
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.
NTP (RFC 1305) is similar to Time (RFC 868) .
Select None to enter the time and date manually.
IP Address or URL Enter the IP address or URL of your time server. Check with your ISP/network
administrator if you are unsure of this information.
Time and Date Choose the time zone of your location. This will set the time difference between
your time zone and Greenwich Mean Time (GMT).
Daylight Savings Select this option if you use daylight savings time. 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.
Start Date Enter the month and day that your daylight-savings time starts on if you selected
Daylight Savings .
