Use Time Server

When Bootup

Select the time service protocol that the timeserver uses. Not all time servers

support all protocols, so you may have to use trial and error to find a protocol

that works. The main differences between them are the time format.
When you select the Daytime (RFC 867) format, the IES-708-22A displays the

day, month, year and time with no time zone adjustment. When you use this

format it is recommended that you use a Daytime timeserver within your

geographical time zone. 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).
None is the default value. Enter the time manually. Each time you turn on the

device, the time and date will be reset to 2000-1-1 0:0.
The IES-708-22A requests time and date settings from the time server under

the following circumstances.
