The first one gives you the timestamp of the point in time we call Reference Point. This is the snapshot we compare against. The amount and speed of change , represented by the Y-Position and size of the bubbles, is measured going forward from that Reference Point.
The second timestamp is the Current Snapshot. The absolute Retail positioning, displayed as the location along the X-Axis, is taken from the snapshot at that point in time.
Did you know: you can also control the slider with the keyboard for even more precision! After dragging the thumb, or simply clicking it, it will be selected, which is shown by a glowing outline. When the thumb is selected, you can use the following keys for control:
- Arrow Up/Down will move the thumb by one time step
- Page Up/Down will move the thumb by ten time steps
- Pos1/End will move the thumb directly to the start/end of the time range
