“Against the clock” describes working quickly to finish before a time limit and can also describe an activity in which elapsed time is recorded to compare speed. This guide keeps those current senses separate from unsupported origin chronology.

“Better late than never” is used when a delayed action, arrival, or improvement is still considered worthwhile because the alternative would be no action at all. This guide does not claim an exact origin date.
“Burn the midnight oil” means to work late into the night. Historical phrase research reports “mid-night oyle” in Francis Quarles’s 1635 Emblemes and an earlier 1623 dictionary entry for working by candlelight, which provides context without proving a single moment of coinage.
