Switch between absolute and relative time: example

When you change the time mode, the Time Bar and individual tag time settings convert between absolute times and relative offsets.

The following table summarizes the states for the Time Bar and three tag offsets/dates for some example data. Tag1 is the currently selected tag. In this example, the actions performed for the different steps are:

1. At exactly 2005-07-04 10:00, "2 hours" is selected from the Time Bar while the Update to Current Time option is enabled. The chart is in absolute mode.

2. The chart is switched to relative time mode.

3. The start and end values are changed in the Time Bar.

4. The chart is switched back to absolute time mode.

   Step:	1	2	3	4
   Mode:	Absolute	Relative	Relative	Absolute
   Time Bar Start:	2005-07-04 8:00	0:00	-0:15	2005-07-04 7:45
   Time Bar End:	2005-07-04 10:00	2:00	0:45	2005-07-04 8:45
   Tag1:	- 24:00	2005-07-03 8:00	2005-07-03 8:00	- 24:00
   Tag2:	0:00	2005-07-04 8:00	2005-07-04 8:00	0:00
   Tag3:	+3:30	2005-07-04 11:30	2005-07-04 11:30	+3:30
   Time Axis Start:	2005-07-03 8:00	0:00	-0:15	2005-07-03 7:45
   Time Axis End:	2005-07-03 10:00	2:00	0:45	2005-07-03 8:45
