Time & date conguration
This page allows you to congure all aspects relating to time and date within the
AdderView CATx IP unit.
Timezone specier
Optionally enter a recognised timezone specier related to the current position
of the AdderView CATx IP unit. When an NTP server is used, the specier will be
used to provide the correct real time.
The timezone specier 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 specication describes when Daylight Saving Time is
in effect. The start eld is when Daylight Saving Time goes into effect and
the end eld is when the change is made back to standard time. The most
common format used for the daylight saving time is: Mm.w.d
Where: m species 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 rst week in which day d occurs, and week 5 species the
last d day in the month.
The time elds 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 (2006): EST5EDT,M4.1.0/2,M10.5.0/2
US Pacic (2006): PST8PDT,M4.1.0/2,M10.5.0/2
US Eastern (from 2007): EST5EDT,M3.2.0/2,M11.1.0/2
US Pacic (from 2007): PST5PDT,M3.2.0/2,M11.1.0/2

Time and Date
