tsequence_value_at_timestamp1() Datum tsequence_value_at_timestamp1 ( const TInstant *  inst1, const TInstant *  inst2, bool  linear, TimestampTz  t  ) Returns the base value of the segment of the temporal value at the timestamp. Parameters [in] inst1,inst2 Temporal values defining the segment [in] linear True when the segment has linear interpolation [in] t Timestamp Precondition The timestamp t satisfies inst1->t <= t <= inst2->t Note The function creates a new value that must be freed
