The Network Time Protocol (NTP) and daylight saving time parameters are described in
the table below.
NTP and Daylight Saving Time Parameters
Parameter Description
NTP Parameters
Note: For more information on Network Time Protocol (NTP), see 'Simple Network Time Protocol
Support' on page 111 .
Web: NTP Server DN/IP
EMS: Server IP Address
[NTPServerIP]
Defines the IP address (in dotted-decimal notation or as an FQDN) of
the NTP server. The advantage of using an FQDN is that multiple IP
addresses can be resolved from the DNS server, providing NTP server
redundancy.
The default IP address is 0.0.0.0 (i.e., internal NTP client is disabled).
Web: NTP Secondary
Server IP
[NTPSecondaryServerIP
]
Defines a second NTP server's address as an FQDN or an IP address
(in dotted-decimal notation). This NTP is used for redundancy; if the
primary NTP server fails, then this NTP server is used.
The default IP address is 0.0.0.0.
Web: NTP UTC Offset
EMS: UTC Offset
[NTPServerUTCOffset]
Defines the Universal Time Coordinate (UTC) offset (in seconds) from
the NTP server.
The default offset is 0. The offset range is -43200 to 43200.
Web: NTP Update Interval
EMS: Update Interval
[NTPUpdateInterval]
Defines the time interval (in seconds) that the NTP client requests for a
time update.
The default interval is 86400 (i.e., 24 hours). The range is 0 to
214783647.
Note: It is not recommend to set this parameter to beyond one month
(i.e., 2592000 seconds).
Daylight Saving Time Parameters
Web: Day Light Saving
Time
EMS: Mode
[DayLightSavingTimeEn
able]
Enables daylight saving time.

[0] Disable (default)

[1] Enable
Web: Start Time or Day of
Month Start
EMS: Start
[DayLightSavingTimeSt
art]
Defines the date and time when daylight saving begins. This value can
be configured using any of the following formats:

Day of year - mm:dd:hh:mm , where:

mm denotes month

dd denotes date of the month

hh denotes hour

mm denotes minutes
For example, "05:01:08:00" denotes daylight saving starting from
May 1 at 8 A.M.

Day of month - mm:day/wk:hh:mm , where:

mm denotes month (e.g., 04)

day denotes day of week (e.g., FRI)

wk denotes week of the month (e.g., 03)

hh denotes hour (e.g., 23)

mm denotes minutes (e.g., 10)
For example, "04:FRI/03:23:00" denotes Friday, the third week of
