Time & date conguration
This page allows you to congure all aspects relating to time and date within the
MC5-IP unit.
Timezone specier
Optionally enter a recognised timezone specier related to the current position
of the MC5-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
Use the arrow buttons to set the correct current time.
Use NTP
When this option is selected, the MC5 will synchronise its internal clocks using
information from the (Network Time Protocol) server listed in the NTP Server IP
address eld.
NTP Server IP address
Optionally enter the IP address for a known Network Time Protocol server.
Set Time from NTP Server
Click to immediately use the time and date information from the listed NTP server.
