The Wikipedia article Trusted Timestamping states that we can timestamp data by publishing it's hash. Publishing can be done either independently or via a third-party publisher, as explained by DrLector on another thread.

However, can we timestamp data without the capability to publish anything?

What solutions can a person (or a computer) employ to timestamp data if it is not connected to the internet for several days or weeks?
