Select the time service protocol that your time server sends when you turn on the
Prestige. 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).
Select None to enter the time and date manually.
Enter the IP address or URL of your time server. Check with your ISP/network
administrator if you are unsure of this information (the default is tick.stdtime.gov.tw).
Choose the time zone of your location. This will set the time difference between your
time zone and Greenwich Mean Time (GMT).
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.
Enter the month and day that your daylight-savings time starts on if you selected
Daylight Savings.
Enter the month and day that your daylight-savings time ends on if you selected
Daylight Savings.
Select this option to have your Prestige use the time server (that you configured
above) to set its internal system clock.
Please wait for up to 60 seconds while the Prestige locates the time server. If the
Prestige cannot find the time server, please check the time server protocol and its IP
address. If the IP address was entered correctly, try pinging it for example to test the
connection.
This field displays the date of your Prestige.
Each time you reload this page, the Prestige synchronizes the time with the time
server.
