GnoTime Alternatives

GnoTime

GTT is a to-do list/diary/journal tool that can track the amount of time spent on projects, and, among other things, generate reports and invoices based on that time.
It's being used to keep shopping lists, organize ideas, track bug reports, keep a diary of activities, do some blogging, provide weekly status reports to management, and even as a consultant billing system.
The reason it can be used for all of these things is that it supports five basic, simple features:

1 Multiple To-Do Lists.
2 A pair of Diary/Journal areas that can be used to keep long and detailed notes and diary entries.
3 A Running Timer, with time totals, for each project/task.
4 A Billing Status dialog for each diary entry.
5 A half-dozen different HTML Reports that can slice and dice your lists.
