Re: [RFC 5/5] Date Mode: Tests

I'd like to have part of the tests in this patch at the beginning of the
series to document and protect the behaviour of the current --date related
options, then your enhancement that adds --zone that lets the users
specify the timezone and the format independently, and finally the
remainder of this patch as an addition to the test script to document and
protect the interaction between the two options (e.g. what happens when
none or only one is specified? what happens when conflicting options such
as "--date=local --zone=gmt" is given?).

Thanks.
