Meaning
When a situation is judged later, calmly, soberly and realistically, once emotion, enthusiasm, drink or the heat of the moment has faded; typically of plans, promises or decisions that looked better at the time than they do afterwards. Neutral, slightly rueful register; standard in journalism and reflective writing. Regional use: General English.
Origin
The phrase joins two old contrasts: daylight as clarity, and cold as dispassionate. Wiktionary, following Christine Ammer's American Heritage Dictionary of Idioms, explains the cold as impartial and unemotional and the allusion as seeing a situation more clearly in daylight once time has passed. The earliest citation it prints is Anna Mary Howitt's An Art-student in Munich (1853), still essentially the literal daylight sense; its earliest clearly figurative quotation is from 1912, Burton Egbert Stevenson's The Mystery of the Boule Cabinet, in which a plan made at night looks preposterous by day. The wording therefore surfaces in the 19th century and the familiar sober-second-thought use is established by the early 20th century, after which it becomes a standard journalistic reflection phrase.
