[Definition of time value in the MR Trace window]
The time value in the MR Trace window indicates the execution elapsed time which sets the program
execution start point to 0 in all the cases.
On the contrary, a numeric value above the grid line (scale) in the MR Trace window is a relative
value which sets the start marker to 0 (the grid interval is specified in the Value dialog), which has
nothing to do with the time value. (It is provided so that you can see the window easily.)
