Rob Farnell also notes that this list could include time worked summaries: http://www.cerb4.com/forums/showpost.php?p=6368&postcount=3

Verified implemented as of dev build 812.

I think both of these requests are handled pretty well by two reports we have available. Both are accessed by turning on the 'Reports' plugin via 'helpdesk setup' -> 'Features & Plugins' and then clicking 'reports' in the main menu at the top.

Hi, a helpdesk user has requested this functionality.
Being able to view tickets they have worked on on certain days is very helpfull for timekeeping.

Answer: WORKER HISTORY report

2) rfarnell quote:
Just a suggestion, but providing information from the "to be included" time tracking plugin http://www.wgmdev.com/jira/browse/CHD-197 which is due for milestone 20 would make sense. E.g. display the the tickets worked on and a figure next to it with the accumulated time worked on that ticket.

Would be a good cue to remind users to keep their time tracking details in order if they forget.

Answer: TIME SPENT PER WORKER report
