Time & date configuration
This page allows you to configure all aspects relating to time and date within the unit.
Timezone specifier
Optionally enter a recognized timezone specifier related to the current position of the
ALIF 2112T unit. When an NTP server is used, the specifier will be used to provide the
correct real time.
The timezone specifier takes the following form:
std
offset
dst
[
offset
]
,
start
[
/
time
]
,
end
[
/
time
]
The
std
and
offset
specify the standard time zone, such as GMT and 0, or CET and -1,
or EST and 5, respectively.
The
dst
string and
[
offset
]
specify the name and offset for the corresponding Daylight
Saving Time zone; if the
offset
is omitted, it defaults to one hour ahead of standard time.
The remainder of the specification describes when Daylight Saving Time is in effect. The
start
field is when Daylight Saving Time goes into effect and the
end
field is when the
change is made back to standard time. The most common format used for the daylight
saving time is:
M
m
.
w
.
d
Where:
m specifies the
month and must be between
1
and
12
. The day
d
must be
between
0
(Sunday) and
6
. The week
w
must be between
1
and
5
; week
1
is the first
week in which day
d
occurs, and week
5
specifies the
last
d
day in the month.
The
time
fields specify when, in the local time currently in effect, the change to the other
time occurs. If omitted, the default is
02
:
00
:
00
.
Typical examples are:
UK:
GMT0BST,M3.5.0/1,M10.5.0/2
Central Europe:
CET-1CEST,M3.5.0/2,M10.5.0/3
US Eastern:
EST5EDT,M3.2.0/2,M11.1.0/2
US Pacific:
PST5PDT,M3.2.0/2,M11.1.0/2

use NTP
When this option is selected, the ALIF 2112T will synchronize its internal clocks using
information from the (Network Time Protocol) server listed in the
NTP Server IP address
field.
NTP Server IP address
Optionally enter the IP address for a known Network Time Protocol server.
