Chapter 8 General Setup Table 10 General Setup (continued) LABEL DESCRIPTION Use Time Server when Bootup Enter the time service protocol that your 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. The MM-7201 requests time and date settings from the time server in the following circumstances: • When the MM-7201 starts up. • In 24-hour intervals after starting. • When you click Apply in this screen. When you select the Daytime (RFC 867) format, the switch 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. When you enter the time settings manually, the MM-7201 uses the new setting when you click Apply. Each time you turn on the switch, the time and date will be reset to 1970-1-1 0:0. Time Server IP Address Enter the IP address of your timeserver. The switch searches for the timeserver for up to 60 seconds. If you select a timeserver that is unreachable, then this screen will appear locked for 60 seconds. Please wait. Current Time This field displays the time you open this menu (or refresh the menu). New Time (hh:mm:ss) Enter the new time in hour, minute and second format. The new time then appears in the Current Time field after you click Apply. Current Date This field displays the date you open this menu. New Date (yyyy- Enter the new date in year, month and day format. The new date then appears in mm-dd) the Current Date field after you click Apply. Time Zone Select the time difference between UTC (Universal Time Coordinated, formerly known as GMT, Greenwich Mean Time) and your time zone from the drop-down list box. Daylight Saving 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. Select this option if you use Daylight Saving Time. Start Date Configure the day and time when Daylight Saving Time starts if you selected Daylight Saving Time. The time is displayed in 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 2:00. 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 and the last field depends on your time zone. In Germany for instance, you would select 2:00 because Germany's time zone is one hour ahead of GMT or UTC (GMT+1). 68 MS-7206 User's Guide

Use Time Server
when Bootup
Enter the time service protocol that your 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.
The MM-7201 requests time and date settings from the time server in the following
circumstances:
When the MM-7201 starts up.
In 24-hour intervals after starting.
When you click
Apply
in this screen.
When you select the
Daytime (RFC 867)
format, the switch 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. When you enter the time
settings manually, the MM-7201 uses the new setting when you click
Apply
. Each
time you turn on the switch, the time and date will be reset to 1970-1-1 0:0.
Time Server IP
Address
Enter the IP address of your timeserver. The switch searches for the timeserver for
up to 60 seconds. If you select a timeserver that is unreachable, then this screen
will appear locked for 60 seconds. Please wait.
Current Time
This field displays the time you open this menu (or refresh the menu).
New Time
(hh:mm:ss)
Enter the new time in hour, minute and second format. The new time then appears
in the
Current Time
field after you click
Apply
.
Current Date
This field displays the date you open this menu.
New Date (yyyy-
mm-dd)
Enter the new date in year, month and day format. The new date then appears in
the
Current Date
field after you click
Apply
.
Time Zone
Select the time difference between UTC (Universal Time Coordinated, formerly
known as GMT, Greenwich Mean Time) and your time zone from the drop-down list
box.
Daylight Saving
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.
Select this option if you use Daylight Saving Time.
Start Date
Configure the day and time when Daylight Saving Time starts if you selected
Daylight Saving Time
. The time is displayed in 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
2:00
.
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
and the last field depends on your time zone. In Germany for
instance, you would select
2:00
because Germany's time zone is one hour ahead
of GMT or UTC (GMT+1).
