Time & date configuration
This page allows you to configure all aspects relating to time and date within the
AdderView CATxIP 5000 unit.
Timezone specifier
Optionally enter a recognised timezone specifier related to the current position
of the AdderView CATxIP 5000 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

Time and Date
Use the arrow buttons to set the correct current time.
Use NTP
When this option is selected, the AdderView CATxIP 5000 will synchronise 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.
