p4 changes @2018/09/27,@now is working, but I want to know the change in certain directory like //A/B
p4 changes @2018/09/27,@now //AA/B... and
p4 changes //AA/B... @2018/09/27,@now are not working, only returns all the changes from the beginning.
It's one parameter:
p4 changes //AA/B/...@2018/09/27,@now
If you pass it as two separate parameters, first you'll get all changes matching the first one, then all changes matching the second. What you want is all changes that match the entire set of restrictions.
