GNU Foliot is a small and easy to use time keeping application.

It can be used in a single user mode or by small organizations. Starting with version 0.9.4, it can import other user's database, an essential feature for remote collaborators.

The fields it handles are: a date, who, for whom, what, a duration, whether or not to be charged and a description.

It includes, on the main application screen, a powerful dynamic filters criteria mechanism, which lets you visualize, work on and print a subset of your time keeping entries.

A printing templates system allows you to (pre)define, reuse and hence quickly generate the pdf files and/or printed reports of your needs.

A version which will let users export an active filter based subset of their time keeping entries is under work.

The name

Foliot was the name given, back in the 13th century, to one of the essential components of the first all-mecanical clocks:

... Starting in the 13th century, large tower clocks were built in European town squares, cathedrals, and monasteries. They kept time by using the verge escapement to drive a foliot, an horizontal bar with weights on the ends, a primitive type of balance wheel, to oscillate back and forth. The rate of the clock could be adjusted by sliding the weights in or out on the foliot bar ... [see here for a complete definition].

What else

GNU Foliot is written in Guile, an interpreter and compiler for the Scheme programming language. It uses Guile-Gnome for its graphical interface, SQLite for its database backend and LaTex for the reports.


GNU Foliot also has a Savannah project page.
