Calculation of time difference for consecutive date rows in Qliksense

[KRM2]

How to get the time difference for consecutive rows in Qliksense expression?

I am trying to get the difference between 1st row-2nd row & 2nd row - 3rd row and so on in Qliksense using expression. load_date_est is the field used for Load time column. 

I tried using expression  ''Interval(load_date_est - Below(load_date_est)'' but not getting any result. 

Any help on this is much appreciated.

have you tried above function instead of below?

try this: Interval(load_date_est - Above(load_date_est))

Yes,I tried using Above as well but in vain. I tried various expressions but not getting the desired result.
