Finding time_units using REST

Hi!

Okay, almost done with a nice billing tool. As promised I will put it in a public repo.

But for some reason the url ticket_articles/by_ticket/"+str(id)+"?sort_by=created_at"
does not return any time_units although mentioned in the documentation (even with : expand=true)

Any and all hints highly appreciated.

Kind regards,
Jeroen Baten
