test_BokkyPooBahsDateTimeLibrary

Testing https://github.com/bokkypoobah/BokkyPooBahsDateTimeLibrary using:

Parity 1.11.1 testnet (parity --no-persistent-txqueue --chain dev)

Ruby 2.4.2p198 on Windows 10, using the Ethereum.rb gem

Note that the number of requests handled by the Parity node was less than 100 per second, which limits the extent of testing possible.
