Do not swallow IOException in System.in.read
Add new static method parseTime (no-op)

TODO: implement parser
Merge remote-tracking branch 'origin/master'
Upgrade JUnit from built-in 4.10 to external 4.11

We need that later for parametrised tests which are also named.
Import org.junit.Assert, not deprecated junit.framework.Assert
Make parseTime public so we can unit test it
Add parametrised tests for (il)legal time formats
