Is there a way to check the time taken for the completion of assignments without using History Instances.
Time Taken for Assignment Completion

There is pyResolvedTime property on clipboard (primary page) which shows Date and Time Resolved - Sum of New, Open, and Pending time spent on item.

if you wish to track for each assignment of the work object, I think there is no direct approach as such but you can do it with some simple logic.
get the start time from pxCreateDateTime property of pyPortal Page(the datetime when the assignment started/opened ),end time will be your currentdatetime make the difference and you will get the time taken for each assignment.this logic you can implement in data transform or activity which will run at the time of post processing.
in case this should happen for all the assignments of the work object, just try to figure out any py data transform or activity which will run at the time of assignment completion.
