+ Use 64-bit integer storage for datetimes and intervals, rather
+ than the default floating-point storage. This reduces the range
+ of representable values but guarantees microsecond precision across
+ the full range (see <xref linkend="datatype-datetime"> for more
+ information). Note also that the integer datetimes code is newer
+ than the floating-point code, and we still find bugs in it from time
+ to time.
