I sometimes work on two or three projects in a week. Each week I need to fill out timesheets.
It would be nice if I could look at the commit logs, and give myself a reminder about when I worked on things. (i.e. : if the commit time was 1pm, then I can assume that I worked for about 4 hours that day on a specific project).
Push time doesn't matter to me at all, btw. The history of the project commits are more important.
