I've been thinking of a project for the blockchain that uses EOS network nodes to monitor time changes for accurate time zone info. Right now the Olson tz database is the largest online solution for correct time keeping based upon IP addresses and zone names, but the process of submitting changes is manual and sometimes after the fact of a time change standard. This blockchain would be able to monitor the actual standards used based upon location and make corrections based upon consensus.

Authority typically makes these decrees now which leaves coders with the mess of updating their software. I think this blockchain might be able to make updates more automatic.
