It will be more efficient to narrow the set of keys to evaluate than look at
all of them and evaluate the timestamp.

UNOFFICIAL

Is the TimestampFilter an efficient means of filtering results by time
ranges?  I have the option of extending the existing rowid's, currently
pre-fixed with yyyymmdd, to include hhmm also, or make use of the
TimestampFilter.  In a quick google search someone mentioned that the
TimestampFilter was inefficient is this correct?
