LABEL DESCRIPTION
Time Server
Use Time Server
when Bootup
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.
Time Server IP
Address
Enter the IP address of your time server. Check with your ISP/network administrator
if you are unsure of this information (the default is tick.stdtime.gov.tw).
Time Zone 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
