Consultants: How do you track your time?

[Descartes]

I often consult on software projects for architecture/implementation/etc.. As such, I'm out of the office quite a bit. I have to keep an accurate representation of my time when invoicing my clients, but the tracking methodology I currently employ is simply too invasive. I often get inundated with questions/requests whether I'm at home, on the road, at the office, etc..

I've used my Pocket PC, my laptop, a voice recorder, an organizer, ad nauseum. All of them work, but they simply take too much time (thus destroying my concentration).

I will write my own software if I can find something that works well...

Any ideas?

I must come up with the most uninteresting topics 🙁 😀
