Borrowed from Latin, from the verse Georgica which was written by the Roman poet Virgil which is sed fugit interea fugit irreparabile tempus (“but it flees meanwhile: irretrievable time flees”) which has the less literal translation "while, the irreplaceable time escapes".
- (phrasal, idiomatic) time flies (used as an alternative to this phrase).
- "Meanwhile, the irreplaceable time escapes", expressing concern that one's limited time is being consumed by something which may have little intrinsic substance or importance at that moment.
