dependant on the current date and time settings of the gateway.
Such facilities work properly only if the Gateway is set with correct
date and time value. For local time, refer chapter RTC Parameters.
• DST is Daylight Saving Time, which is the new local time, a region
is assigned for a period of the year, usually an hour forward from its

the beginning of the daylight saving time and delayed at the end of
day light saving time.
