Default: UTC-0:00 (Lisbon, London)
This setting enables the conversion of UTC (Universal Coordinated Time) to local time.
DST Offset
Synopsis: HH:MM:SS
Default:00:00:00
This parameter specifies the amount of time to be shifted forward/backward when DST
begins and ends. For example, for most of the USA and Canada, DST time shift is 1 hour
(01:00:00) forward when DST begins and 1 hour backward when DST ends.
DST Rule
Synopsis: mm.n.d/HH:MM:SS mm.n.d/HH:MM:SS
Default:
This parameter specifies a rule for time and date when the transition between Standard
and Daylight Saving Time occurs.
• mm - Month of the year (01 - January, 12 - December)
• n - week of the month (1 - 1st week, 5 - 5th/last week)
• d - day of the week (0 - Sunday, 6 - Saturday)
• HH - hour of the day (0 - 24)
• MM - minute of the hour (0 - 59)
• SS - second of the minute (0 - 59)
Example: The following rule applies in most of the USA and Canada:
03.2.0/02:00:00 11.1.0/02:00:00
In the example, DST begins on the second Sunday in March at 2:00am, and ends on the
first Sunday in November at 2:00am.
Current UTC Offset
Synopsis: 0 s to 1000 s
Default: 34 s
Coordinated Universal Time (UTC) is a time standard based on International Atomic
Time (TAI) with leap seconds added at irregular intervals to compensate for the Earth's
slowing rotation. The Current UTC Offset parameter allows the user to adjust the difference
between UTC and TAI. The International Earth Rotation and Reference System Service
(IERS) observes the Earth's rotation and nearly six months in advance (January and July)
a Bulletin-C message is sent out, which reports whether or not to add a leap second in
the end of June and December.
Please note that change in the Current UTC Offset parameter will result in a temporary
disruption in the timing network.
