1996-12-19T should not be a valid ISO8601 string

[francois-normandin]

referencing #17 , the time designator cannot be alone and not followed by an empty time string.
We can possibly accept it with strict = false as it is unambiguously a date, but then, should time be inferred as 00:00:00?

I agree with your assessment. It is also nonsensical that a time designator [T] would be included in a date-only string. I think it should not be a valid string - even if strict==false.

We can possibly accept it with strict = false as it is unambiguously a date, but then, should time be inferred as 00:00:00?

In the case of date string to timestamp, good question what should be the default time, presumably the developer is planning to ignore it anyway. I think 00:00:00 is reasonable.
