From the developer:
ActivityChanger modifies the timetable of an activity in MSTS. ActivityChanger executes this process fully automatically, simply by changing the Start Time of the
Activity. Another feature is "rounding the player timetable" for more realistic arrival and departure times, since real trains do not start at 8:15:53 but at 8:16:00. You can round all of the arrival and departure times to the nearest 10, 15, 30 or 60 seconds with one button.
You may want to check out more software, such as OfflineList, Smart Mod Manager or Redblade, which might be similar to ActivityChanger.
