Calculate difference in time between dates in same column

Hi Anonymous 

The OFFSET function would work well here.

To come up with the exact DAX expression, we would need to clarify:

• What determines the sort order? I can see the dates in your image are not in ascending/descending order. Is there another column partitioning or defining the sort order?
• Do you want a measure (which would respond to filters) or a calculated column?
  In the case of a measure, we would need to clearly define which dates are included, for example it could be all dates visible in the filter context, or all dates for which certain measure(s) are nonblank.
