Algorithm to shift wall-clock time in events

[Peter Peterson]

In anticipation of an upcoming pulsed magnet experiment, create a new algorithm that can add a constant to all wall-clock times in a workspace.

(In [10501]) Fixes #2750: Algorithm to shift wall-clock time in events.

Load("/MANTID/Test/AutoTestData/CNCS_7860_event.nxs", "CNCS_7860_event")
ChangePulsetime("CNCS_7860_event", "CNCS_7860_event-shift", 100.0)
Rebin("CNCS_7860_event", "CNCS_7860_event", "4.7e4,10,4.9e4")
Rebin("CNCS_7860_event-shift", "CNCS_7860_event-shift", "4.7e4,10,4.9e4")
plotSpectrum(["CNCS_7860_event", "CNCS_7860_event-shift"], 2)

From what I can see, this algorithm doesn't seem to change the events. I would have expected the above script to remove the peak from the "shifted" workspace, but they still match up exactly when plotting it.

[Janik Zikovsky]

The algorithm shifts the pulse time (wall-clock) of the event, not its time of flight. There are no direct ways to view events pulse time in Mantid; but FilterByTime could be used to show it indirectly.
