If you only care about the week (for instance), then a timestamping
service that publishes signatures on a weekly basis doesn't require a
correct clock. In fact, a realistic question might be "did X happen
before Y", and a simple hash list of signatures, published after each
new signature, would suffice. No need for a clock at all.
