No, not a +Ref +List. As I propoesed on Feb 08

   (rel d (+Aux +Ref +Date) (t)) # Date
   (rel t (+Time))               # Time


   (rel ts (+Ref +Bag) ((+Date)) ((+Time)))  # Timestamp

In both cases, the index key will be (<date> <time>). You can use
(collect ..) or Piloq queries.

as usually the block size is sufficiently big.

But the index tree should need fewer blocks (as more entries go into
each block). The PicoLisp B-Trees don't use a fixed number of entries
per block, but fill up each block until it is full and thus needs to be
