Parameter description:
Clock Source:
Select the clock source for the LGB5128A. You can choose “Use local Settings”
or “Use NTP Server” for the LGB5128A time clock source.
Local Time:
Shows the current time of the system.
Time Zone Offset:
Provides the timezone offset relative to UTC/GMT. The offset is given in
minutes east of GMT. The valid range is from -720 to +720 minutes.
Daylight Saving:
Daylight saving is used in some countries. If set, it will adjust the time lag or
advance in unit of hours, according to the starting date and the ending date.
For example, you can set the daylight saving to be 1 hour. When the time
passes over the starting time, the system time will be increased one hour after
one minute at the time since it passed over. When the time passes over the
ending time, the system time will be decreased one hour after one minute at
the time since it passed over.
The switch supports valid configurable daylight saving times between –5 and
+5 steps for one hour. If this parameter is zero, the switch enacts daylight
saving time. You don’t have to set the starting/ending date as well. If you set
daylight saving to be non-zero, you have to set the starting/ending date as well;
otherwise, the daylight saving function will not be activated.
