The Gantt chart resolution only displays down to days.  Please increase the display resolution to milliseconds.  The start time already handles milliseconds (start: new Date("2014-06-02T00:10:10.000Z").  We just need the resolution to enable us to see the tasks in the minutes, seconds, milliseconds time frame.  Additionally, you should be able to zoom in using the mouse.  Many of your charts already have these features.  An upgraded Gantt chart would be an incredible capability for engineers as well as the military to plan and schedule tasks at the millisecond range.  Thanks for your time.
