How to skip Same dates in Column and Consider Next Max dates in DAX

Anonymous You'll need an Index to define "next". Then something along these lines. See my article on Mean Time Between Failure (MTBF) which uses EARLIER: http://community.powerbi.com/t5/Community-Blog/Mean-Time-Between-Failure-MTBF-and-Power-BI/ba-p/339586.
The basic pattern is:
Column = 
  VAR __Current = [Value]
  VAR __PreviousDate = MAXX(FILTER('Table','Table'[Date] < EARLIER('Table'[Date])),[Date])

  VAR __Previous = MAXX(FILTER('Table',[Date]=__PreviousDate),[Value])
RETURN
 ( __Current - __Previous ) * 1.

Hi Anonymous 

Thanks for the solution Greg_Deckler  provided, and i want to offer some more information for you to refer to, based on your description, you should want to get the next start time greater than the current end time if the current end time is greater than the start time of the next row? if you want to achieve this, you can refer to the following solution.

first,  as Greg_Deckler  mentioned, you need to have an index column, then you can create the measure below.

MEASURE =
VAR _nextstarttime =
    CALCULATE (
        MAX ( 'Incident'[Actual Start CST] ),
        ALLSELECTED ( 'Incident' ),
        'Incident'[Index]
            = MAX ( 'Incident'[Index] ) + 1
    )
VAR _index =
    CALCULATE (
        MIN ( 'Incident'[Index] ),
        ALLSELECTED ( 'Incident' ),
        'Incident'[Actual Start CST] > MAX ( 'Incident'[END Time CST] ),
        'Incident'[Index]
            > MAX ( 'Incident'[Index] ) + 1
    )
RETURN
    IF (
        MAX ( 'Incident'[END Time CST] ) > _nextstarttime,
        CALCULATE (
            MAX ( 'Incident'[Actual Start CST] ),
            ALLSELECTED ( 'Incident' ),
            'Incident'[Index] = _index
        ),
        _nextstarttime
    )
