In order to make the modification visible, it is necessary to call the Draw method.
If a relative time interval is displayed by the time axis (the date is not shown, on the time axis there is the time, for example from 0 sec to 10 sec), then the time must be set explicitely with stating the data type, oTView.TimeMin = CDate(0), oTView.TimeMax = CDate(10/24/3600), which corresponds to the range of the time axis from 0 to 10 seconds.
oTView.TimeSetType = 1
oTView.TimeMin = t 'local time
oTView.TimeSetType = 2
oTView.TimeMin = t 'standard time
