Initializing a `CalDateTime` instance with midnight time is treated as `date-only`

ical.net/Ical.Net/DataTypes/CalDateTime.cs

Lines 91 to 93 in 533aeeb

	Value = new DateTime(value.Year, value.Month, value.Day, value.Hour, value.Minute, value.Second, value.Kind);
	HasDate = true;
	HasTime = value.Second != 0 || value.Minute != 0 || value.Hour != 0;

The time specification for midnight should not be considered as date-only when initializing a CalDateTime instance.
Also, when the underlying DateTime Value is set to a new value without updating CalDateTime,HasTime this becomes an ambiguity, users may not be aware of.
Both can lead to unexpected behavior, e.g. in terms of (but not limited to) recurrences.
