Detailed Description

Functions for time types based on TimestampTz, that is, TimestampSet, Period, and PeriodSet.

The Period type is a specialized version of the RangeType in PostgreSQL. It is considerably more efficient, in particular because it is a fix-length type, it has finite bounds, and do not allow empty periods. The TimestampSet type represents sets of disjoint TimestampTz. The PeriodSet type represents sets of disjoint Period values.
