Can I somehow differentiate between:

DateTime->new(year=>2017, month=>6, day=>16)

and

DateTime->new(year=>2017, month=>6, day=>16, hour=>0, minute=>0, second=>0)

My problem: user might enter 2017-06-16 or 2017-06-16T00:00:00 and in the case of the former I want to set the default for hour/minute/second to 23/59/59 respectively. However, I am checking at a position where the date has been converted to DateTime object.
