all-time
Synonym discussion
Sense: adjective/1
All four words describe levels or moments that stand out across a long span of time, but they sit in different registers. All-time is the everyday choice and almost always pairs with a superlative noun: an all-time high, my all-time favourite. Record is more neutral and statistical — a record harvest, a record turnout — and works well in news reports without emotion. Historic carries weight: it tells the reader the moment will be remembered (a historic vote, a historic peace deal), not just that a number is large. Unprecedented is the most formal and means simply that nothing of this kind has happened before; it does not have to be a high or a low. Compare: 'Sales hit an all-time high' (casual peak), 'Sales reached a record high' (data report), 'It was a historic moment for the company' (memory, not numbers), 'The flooding was unprecedented' (formal, no direction implied).

Etymology
A 20th-century compound built from the everyday English words 'all' and 'time'. The phrase began appearing in American sports and business writing in the early 1900s, where journalists needed a quick way to say 'the highest (or lowest) figure in the whole history of something'. The hyphenated adjective form spread from that journalistic shorthand into general use, and today it pairs almost exclusively with superlatives such as high, low, best, and favourite.
