Hi,

I am extracting time values from web datatable column and I am getting time value as for ex.7:24 and its in string. Also I am able to convert it into datetime and its appearing as for ex. 11/23/2017 07:24:00.I want to calculate average of such time values from web datatable column. Any suggestion?
