Seems the best way around this is to introduce precision. This way we can 
limit datatime field to store year, date or time.

This is also useful since some formats like ID3 provide Year tag. Precision 
allows us to discern between content created on 1st Jan of some $Year and 
content created in $Year with precise date unknown.

Exclusive ranges are easily eliminated with the help of precision.
