tinstantset_value_at_timestamp() bool tinstantset_value_at_timestamp ( const TInstantSet *  ti, TimestampTz  t, Datum *  result  ) Returns the base value of the temporal value at the timestamp. Note In order to be compatible with the corresponding functions for temporal sequences that need to interpolate the value, it is necessary to return a copy of the value
