This field displays the last updated date from the time server or the last
date configured manually.
When you set Time and Date Setup to Manual, enter the new date in
this field and then click Apply.
Select this radio button to have the P-792H v2 get the time and date
from the time server you specified below.
Select the time service protocol that your time server sends when you
turn on the P-792H v2. 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).
Enter the IP address or URL (up to 20 extended ASCII characters in
length) of your time server. Check with your ISP/network administrator
if you are unsure of this information.
Choose the time zone of your location. This will set the time difference
between your time zone and Greenwich Mean Time (GMT).
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.
Configure the day and time when Daylight Saving Time starts if you
selected Enable Daylight Saving. The o'clock field uses the 24 hour
format. Here are a couple of examples:
Daylight Saving Time starts in most parts of the United States on the
second Sunday of March. Each time zone in the United States starts
using Daylight Saving Time at 2 A.M. local time. So in the United States
you would select Second, Sunday, March and type 2 in the o'clock
field.
Daylight Saving Time starts in the European Union on the last Sunday
of March. All of the time zones in the European Union start using
Daylight Saving Time at the same moment (1 A.M. GMT or UTC). So in
the European Union you would select Last, Sunday, March. The time
you type in the o'clock field depends on your time zone. In Germany
for instance, you would type 2 because Germany's time zone is one
hour ahead of GMT or UTC (GMT+1).
