Was heure définitive really UT2? My French is pretty weak, but page 253 of your source has a table entitled "Temps Universel 2 - Heure Définitive", which makes it appear to be listing the difference between UT2 and heure définitive.
No, I think that’s a dash in that table heading, not a minus sign. In other words, the two phrases are synonyms. That is supported by the text on slide 5 (page 258), just below the middle, which says “Les heures définitives (TU2)...”. paul
