Setting the Mode for the Clock Manager
1.
In the
Manage System
tab (FIG. 33), select a
Time Sync
option.
Network Time
: This option allows the Master to manage it’s clock by connecting to a NIST (Internet Time Service) Server.
When this option is selected, the Master will connect to the default NIST Server to get date and time information.
You can select a different NIST Server (or specify the IP Address of a known NIST Server) in the
NIST Server Manager
section (see the
Selecting a Custom NIST Server
Stand Alone
: This option lets the Master use its own internal clock. When this option is selected, two additional fields are

Setting Daylight Savings Rules
1.
In the
Daylight Savings Time Manager

reveals additional Daylight Savings options.
2.
Use the
Offset
drop-down menus to adjust the amount of time (hours and minutes) to offset Daylight Savings. By default, the
offset is set to 1 hour.
NOTE:
Although most places that support Daylight Savings usually adjust the local time by one hour this doesn't cover all locations.
To provide flexibility for such locations it is possible to configure a different daylight savings time offset.
3.
Use the
Starts
fields to specify when Daylight Savings should start. The Starts rules include:
Select
Fixed
to specify the calendar date when the rule applies as a specific date ("March 21"). When
Fixed
is selected, use
the
Day
,
Month
,
Hours,
and
Minutes
fields to specify the date and time (hh:mm) to start Daylight Savings time.
Select

Day
,
Month
,
Hours
, and
Minutes
fields to specify the occurrence to
start Daylight Savings time.
The range for

Last
indicates the last occurrence of a particular day of the
month. This is to accommodate months that include four weeks as well as those that include five.
4.
Use the

fields to specify when Daylight Savings should end. The Ends rules match the Start rules, and follow the same
logic. Select
