Fix up the zeroTime() function. Calendar has two unique fields that store

hour data for some reason, which are both set when one does
Calendar.getInstance(), so we need to change both of them if we actually
want the hour to change.  Also change to explicitly set the fields to
zero, since clear isn't setting them to zero but to 'undefined' which
happens to be interpreted as zero.  Might as well be explicit about what
we want.
