e) **Global versus local**: Time4J rejects the design idea of JSR-310 to separate between "machine time" and "human time". This is considered as artificial. So all four basic types offer both aspects in one. For example a calendar date is simultaneously a human time consisting of several meaningful elements like year, month etc. and also a kind of machine or technical time counter because you can define a single incrementing number represented by julian days. In a similar way a UTC-moment has both a technical counter (the number of SI-seconds since UTC-epoch) AND a human representation visible in its canonical output produced by `toString()`-method (example: 2014-04-21T19:45:30Z). However, Time4J emphasizes the difference between local and global types. Conversion between these types always require a timezone or an offset.
