Time Protocol 

Select the time service protocol that your timeserver sends when you turn on 

the device. 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 

Address

Enter the IP address or domain name of your timeserver. 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

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.
