slider - Make a time IntervalSlider

I want to make a time interval slider with an initial setting of (10:00:00 Mar. 8 2015, 12:30:00 Mar. 8 2015) and which varies from 00:00:00 Mar. 8 2015 to 22:30:00 Mar. 8 2015 with a granularity of 5 Minutes.

I tried using IntervalSlider in Mathematica 10 like this:

IntervalSlider[{DateString[{2015, 3, 8, 10, 0, 0.}], 
      DateString[{2015, 3, 8, 12, 30, 0.}]}, {DateObject[{2015, 3, 8, 0, 
        0, 0.}], DateObject[{2015, 3, 8, 22, 30, 0.}], 
      Quantity[5, "Minutes"]}] 

but it doesn't work. Any ideas?

Answer

You will need work with an interval slider in terms of AbsoluteTime values because such sliders only work with numeric objects. Here is a demonstration where a interval slider has the behavior you want.

With[{
  min0 = AbsoluteTime @ DateObject[{2015, 3, 8, 10, 0, 0.}],
  max0 = AbsoluteTime @ DateObject[{2015, 3, 8, 12, 30, 0.}],
  minT = AbsoluteTime @ DateObject[{2015, 3, 8, 0, 0, 0.}],
  maxT = AbsoluteTime @ DateObject[{2015, 3, 8, 22, 30, 0.}]}, 
  Manipulate[

    DateString /@ span,
    {{span, {min0, max0}, "Interval"}, minT, maxT, 5 60, 
      ControlType -> IntervalSlider}]]
