Daylight Saving:
Daylight saving is adopted in some countries. If set, it will adjust the time
lag or in advance in unit of hours, according to the starting date and the
ending date. For example, if you set the day light 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. And
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 day light saving time is
–5 ~ +5
step one hour. The zero for this parameter means it need not have to
adjust current time, equivalent to in-act daylight saving. 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.
