Always append timestamp to DUT directory created

Always append timestamp to the directory containing the report. I believe this used to be the case, however, a unit test would fail because the timestamp would change between the generation and the actual verification.

Inspect the code that creates the directory containing the report and the related unit test. First reproduce the mismatch between directory creation and verification timestamps, then trace where the timestamp is generated. Done means the report directory consistently includes the timestamp and the unit test passes without depending on changing timestamps.
