tempus fugit
Time flies Classical Wisdom
Based on Virgil Georgics 3.284: fugit irreparabile tempus (irretrievable time flies)
In Scripture
Angelus autem Domini descendebat secundum tempus in piscinam, et movebatur aqua. Et qui prior descendisset in piscinam post motionem aquæ, sanus fiebat a quacumque detinebatur infirmitate.
And an angel of the Lord descended at certain times into the pond and the water was moved. And he that went down first into the pond after the motion of the water was made whole of whatsoever infirmity he lay under.
Ioannes 5 · 4
