Element Description
Device Time Zone Choose a time zone for the device. These options represent Greenwich
Mean Time (GMT) plus or minus a number of hours.
Note Changing the time zone on the device may drop the connection
to any installed Security Services modules (SSMs).
Daylight Savings Time
(Summer Time)
Choose a daylight savings time option, and if necessary, specify when
and how daylight savings time is applied:
None – Choose this option to disable automatic correction for daylight
savings time.
Set by Date – Choose this option to specify the date and time when
daylight savings time begins and ends for a specific year. If you use this
option, you will need to reset the dates every year.
Set by Day – Choose this option to specify the start and end dates for
daylight saving time using the month, week, and day on which daylight
savings time begins and ends. This option also lets you set a recurring
date range that you do not need to alter yearly.
Set by Date

when daylight savings time starts and ends.
Date Enter the date on which daylight savings time begins or ends, in MMM

calendar icon to select the date from a pop-up calendar.
Hour Choose the hour, from 00 to 23, in which daylight savings time begins
or ends.

ends. You can select a numerical value that corresponds to the week—1
through 4—or you can specify the first or last week in the month by
choosing first or last. For example, if the day might fall in the partial
fifth week, choose last.
