This was an experimental feature that was removed because it never reached maturity. A new approach is in development: https://profiles.tiki.org/Timesheets
Plugin Timesheet
Introduced in Tiki9
Use this wiki plugin to embed the timesheet feature into any page. This timesheet feature allows for tracking time spent on different tasks and projects. It uses a Jquery plugin called JTrack, which allows time counters to remain on even if the user closes the browser or logs out. It can be used for project management, where workers are expected to record the time spent on different tasks.
Parameters
Plugin Manager error: timesheet plugin not found
