What is it for?

Verifying the date in (near-) realtime reporting and live streams. It
does not work against the past (taking snapshots of the code and
using them later) but can be used to verify the date in rapidly
disseminated information.

How does it work?

A timestamp is generated on the server and signed using a private key
to produce a verification signature. The QR code contains a URL with
the timestamp and the signature. The signature can also be verified
using the public key below.
