test(timepicker): add tests for min/max time with date objects
fix(date-parser): set parsed time value attributes date part to Jan 1, 1970

The timepicker time attributes are always a time value based on Jan 1, 1970, so by setting the date part of the parsed min/max time attribute values to that same day, we effectively ignore the date part when validating time selection.
