Figure 20: Time Page
The Time Page contains the following sections:
•
Clock Source — The source used to set the system clock. The possible field values are:
–
None — Indicates that a clock source is not used. The clock is set locally.
–
SNTP — Indicates that the system time is set via an SNTP server.
•
Date — The system date. The field format is Day/Month/Year. For example: 04/May/50 (May 4, 2050).
•
Local Time — The system time. The field format is HH:MM:SS. For example: 21:15:03.
•
Time Zone Offset — The difference between Greenwich Mean Time (GMT) and local time. For example, the
Time Zone Offset for Paris is GMT +1, while the Time Zone Offset for New York is GMT –5.
•
Daylight Savings — Enables automatic Daylight Savings Time (DST) on the device based on the device’s
location. There are two types of daylight settings, either by a specific date in a particular year or a recurring
setting irrespective of the year. For a specific setting in a particular year complete the
Daylight Savings area,
and for a recurring setting, complete the Recurring area. The possible field values are:
–
USA — The device switches to DST at 2:00 a.m. on the first Sunday of April, and reverts to standard
time at 2:00 a.m. on the last Sunday of October.
–
European — The device switches to DST at 1:00 am on the last Sunday in March and reverts to standard
time at 1:00 am on the last Sunday in October. The European option applies to EU members, and other
European countries using the EU standard.
–
Other — The DST definitions are user-defined based on the device locality. If Other is selected, the From
and To fields must be defined.
•
Time Set Offset — Used for non-USA and European countries to set the amount of time for DST (in min-
utes). The default time is 60 minutes.
•
From — Indicates the time that DST begins in countries other than the USA and Europe, in the format Day/
Month/Year in one field and HH:MM in another. For example, if DST begins on October 25, 2007 at 5:00 am,
the two fields should be set to 25/Oct/07 and 05:00. The possible field values are:
–
Date — The date on which DST begins. The possible field range is 1-31.
