An example of such a system is a glorified Excel sheet, given to your manager monthly, where you write how many hours have you worked on a given workday and which project you should report the time on, if you have multiple.

Getting acquainted with the system might take half an hour. Filling it in, in most trivial cases, is a copy-paste that takes up to five minutes a month. In case you have a more complicated case of working times, you should already be accustomed to noting down your work time daily, even if for your own good.
