LPS-45669 - "dateParam" attribute from liferay-ui:input-time should be mandatory or have some default value

Hi @jonmak08,

Attached is an update for https://issues.liferay.com/browse/LPS-45669.

This is one of two bugs I am working on having to deal with the input_time taglib.  They're related but this is the simpler of the two.  I'm still working on the other (https://issues.liferay.com/browse/LPS-45667).

Please let me know if there are any issues.

Thanks!
