(problem most likely in all/most locations where the timebar + paging is present).
go to administration -> audit, either log or actions.
set up displayed rows per page so that there's only one page at 1h, and more than one page with some longer period.

• switch to 1h
• switch to some longer period where there's more than one page
• switch to page 2
• switch to 1h

notice how it went back to the second page, which is quite unexpected and confusing
