Missing periodicIntervalDelta attribute for Release 3
periodicIntervalDelta attribute of timeSeries is missing in TS-0004 release 3. After some investigation, a contribution was agreed for TS-0001 to introduce this attribute (SDS-2019-0253R03-TS0001-Time_Series_New_Attribute_R3 and SDS-2019-0292R02-TS0001-Time_Series_New_Attribute_R4) but there was no corresponding contribution for TS-0004 (neither R3 nor R4).
However, for Release 4, the periodicIntervalDelta was introduced in version 4.7.0 after agreement of contribution SDS-2021-0201R02-TS0004_timeseries_procedures. It was not decided whether or not the update of the timeSeries procedures should be done also for Release 3.
Proposal) To prepare a mirror contribution to SDS-2021-0201R02-TS0004_timeseries_procedures for Release 3 so that the periodicIntervalDelta is added together with the update on the timeSeries procedures.
