Tempus fugit indeed! Where has the week gone?

Tempus fugit means time flees in Latin, and was first recorded in a poem by Virgil (according to Wikipedia). And time has been important in our language ever since.

My Penguin Dictionary of English Idioms has a whole section dedicated to time-related expressions (“time is of the essence!”), while my 1988 second edition of Fowler’s Modern English Usage clarifies some synonyms of time and the relationship between them:

“An aeon is an infinitely long period of time.
A date is the identifiable or intelligibly stated point of time at which something occurs.
An epoch is the date of an occurrence that starts things going under new conditions.
An era is the time during which the conditions started at an epoch continue.
A period is an era regarded as destined to run its course and be succeeded by another.
A cycle is a succession of periods itself succeeded by a similar succession.
A time, and an age, are words often exchangeable with all or most of the above, but less precise in meaning.”

Just so we’re all clear, then. Anyway, must be off, time waits for no man…
