How it’s done?
Our recommendation is to create a new calendar for your time recordings. You could technically use your personal calendar, but once you want to share your time recordings with somebody else, it would be a lot of work to separate all the entries.

Within that calendar you can create new entries representing your work-packages. Every entry must have a tag that identifies the group or project of the work-package. Behind that tag you can leave a comment to document the work you have done.
For example:

Make sure that the entries start-time and end-time matches your actual time consumption. Once you create a report now, all entries of your calendar that are having a #tag in its title will be used to create a report. You are also able to apply filters.
