Order of data returned from the Api

Hi,
I have noticed that timeslips seem to be returned from the API ordered by descending “dated_on” (most recent first) which makes sense, however there is no mention of the specific ordering in the API documentation.

I am currently planning to rely on this ordering when requesting pages of timeslip data from the API, is this likely to change?

What is the specific ordering of other data such as users and projects?

Thanks
