Lost time is never found again

Time discovers truth.

Time is too slow for those who wait, too swift for those who fear, too long for those who grieve, too short for those who rejoice, but for those who love, time is eternity.

Time is the justice that examines all offenders

Defer no time, delays have dangerous ends

Time is an illusion. Lunchtime doubly so

Today is the tomorrow you worried about yesterday

There is a time for departure even when there's no certain place to go

Yesterday is a canceled check; tomorrow is a promissory note today is the only cash you have - so spend it wisely

Don’t count every hour in the day, make every hour in the day count
