How to get user's time logs from API

Hi all

Have reviewed similar tickets, and there seems to be no consensus on if this is possible with the API.  The docs suggest it might be possible to put something together using the Metrics and Audit APIs, but I have poked around with the responses from these APIs and I can't construct anything that will give me the actual time logged by a user on a ticket.

To clarify, I am not looking for total time spent, which is already documented.

I need to extract from the API, the time spent by users on tickets.  I am sure there is a way to construct this from the audit logs, but I can't see how!

Please advise and document this Zendesk!
