[CLI-327] Fix for expected textual date values.

[Claudenw]

Fixes for CLI-327

In some cases the time zone for the expected date string is different than the hard coded version. This change creates the expected value from a known simple date format of the Date argument so that the expected value always matches the produced time zone.

Hi @Claudenw
Thank you for your PR.
The explanation in the description of this PR needs to be a comment in the test to warn people NOT to write the old style of test again.
