4.1.7 Date/Time Parameters (D, T, TO)
The logger date and time is maintained in a battery backed Real Time Clock whose time base is
adjustable by a trim capacitor on the circuit board. Time is displayed in 24 hour format separated by
colons, and the date is displayed as day/month/year with slash separators. When entering the time
and date all fields must be entered. Note that if the time is entered as T= then it will be reset to
midnight 00:00:00.

The Time Offset parameter allows data from loggers in different time zones to be synchronised to a
reference time zone location. If this feature is not required then simply set the time offset to 00:00.
