Real Time Clock; Adjusting The Display Clock - LogTag Recorders TRED30-16R Product User Manual

Real Time Clock

The time shown on the recording display is linked to the recorder's
internal real time clock.
A day change occurs when the display time rolls through midnight (i.e
00:00). This is the primary function of the display clock.
Each time the recorder is configured with LogTag
clock value is set to the PC's current local time (or timezone). The time
can also be adjusted directly on the unit using the buttons (see

Adjusting the Display Clock

below).
Note that the recorder's internal real time clock value is only updated
when the recorder is configured with LogTag
prevents the data logging becoming discontinuous, which would be
the case if the real time clock were to be changed together with the
display clock.

NOTE: It is advised that the real time clock is only adjusted when in
STOPPED or READY modes (i.e not recording) to avoid large shifts in
day boundary data.
If a display clock adjustment is made while in RECORDING mode, the
next log taken will be identified in the downloaded data with a time
change mark.
Changes to the display clock do not affect the internal real time clock
value, so the logged data does not show time gaps.
