Not quite, if you use a timestamping service... They stamp
a message or a message digest with their timestamp and periodically
publish a public table of timestamps.

Exactly what advantage would you have over this service:
They've been in business a long time at this point... I've
never needed to use them, but they've been there for many years...
Your system clock is not an issue. They also post their stamps
to a newsgroup for further "publication and documentation".
