Brooks Harris mentioned, at approximately Sun 1/25/2015 21:02 UT, a "Gregorian timescale". I believe that since in Gregory's time there was no alternative to making the passage of calendar days agree with the day/night cycle, we must understand "Gregorian timescale" to mean either apparent or mean solar time (unless an ecumenical council is called and declares otherwise). Also, I am not at all sure that the Gregorian calendar has always been used together with the convention that the new day begins at midnight; I would like to be pointed to a reference that says that, if it exists.
