Figure 42 Graphical Display with Data Logger
The time that is shown below the graph is adjusted with the current time
offset of the transmitter. If you change the transmitter's date and time
setting, the displayed timestamps in the history graph change
accordingly. For an explanation of the effect of changing the date and
time manually, see section Data Logger Module on page 58.

the exact time difference between the present and the cursor position is
not exactly known.
