I should also mention that Antolius is calculating his daylight hours into their respective 12th parts like the old Babylonian relative method of keeping hours divided approximately 15 degrees separate on the sundial.

So, these are not 'modern' fixed hours, but rather the means to calculate Solstice and Equinox by the sundial. I suppose we should just call it ancient near-eastern and Mediterranean time keeping method, since everyone used it. The Babylonians didn't invent it.

The first number is the hour (simanu in Akkadian) of the day or night, the second unit is measured in uš, the third in gar.

The length of a simanu (seasonal hour) is determined by dividing the length of local daylight by 12, or in the case of a night hour, dividing nightime by 12. For your current location a seasonal daylight hour is equal to 73.9 minutes and a seasonal nighttime hour is equal to 46.1 minutes.
The length of an uš is set at approximately four minutes, or one degree of movement of the sun. For your current location there are 18 uš in a seasonal daylight hour. Coincidentally our 360° circle is based on the definition of an uš as one degree.
The length of a gar is set at approximately four seconds (1/60th of an uš)
