Is there any way to get date time for particular state of a task?
Suppose a task have 4 step
----------------------------------------
step 1(new): yyyy-mm-dd hh:mm:ss
step 2(assign): yyyy-mm-dd hh:mm:ss
step 3(resolve): yyyy-mm-dd hh:mm:ss
step 4(closed): yyyy-mm-dd hh:mm:ss
-----------------------------------
I want to fetch step 2 and step 3 time.
Thanks in advance
