I doubt that the second one is seconds. I also don't think it could be calculated so accurately without a chronometer at that time.
I think it is related to the movement of the moon in relation to the rotation of the earth.
The moon takes about 7 minutes to move once around its diameter.
That means 7 minutes from touching it until the eclipse, and 7 minutes until it has left it again. Equal to 14 minutes.
In these 14 minutes, however, the Earth's rotation also results in a difference that I have to take into account.
14 min + 2 min equals solar eclipse.
Or something like that. I'm not quite sure anymore.
