INRIM can only disseminate time as determined by law or decree or order issued before the fact. What the Romans do is always a different matter, and is difficult to determine 70 years later. Besides, in recent cases where legal time has been observed to differ from widespread usage (eg Turkey), the tz database describes legal time.
For 1967..1979, all steps in the Italian time scale were announced in the "Gazzetta Ufficiale", as required by the law:
Since much before 1967. But the actual laws are extremely confused. I checked one, and it does not agree with INRIM. I trust more the INRIM. This one is about the end of DST for 1944: http://www.normattiva.it/atto/caricaDettaglioAtto?atto.dataPubblicazioneGazz...
Anyway, these sources seem to agree with the tables of INRIM.
The single one I checked does not agree :( (I'll add this to my not yet written email to INRIM) Cheers
