I'm working on improving the quiz module ,for example student attempt each question and
each time the button "submit" is clicked it save id ,answer, qid, in the table called "child _attempt table"
I would like to implement time has to spent answering each question . how to track start time and end time for each question using php
id, eid, studentd_id, attempted_number, start_date, end_date, is_submitted, score
[b]child _attempt table[/b]
id, qid, attempted_id, answer
