Dispensing all kinds of reference

"Excuse me."

I look up from the Reading Room desk to find a very perplexed-looking elderly gentleman. "Yes?"

The man looks at his wristwatch, up at our wall clock (which is still running an hour behind, natch), and back at me. "I was under the impression that this room closed at 10pm."

"We do."

The man looks at his watch again. "Was there some sort of time change that I missed?"

Daylight Savings - always good for at least one chuckle at a public service desk, though usually it's not three whole days afterwards! The frightening thing is that this guy has been running late for everything in his life since Sunday, kind of like Kramer in that episode of Seinfeld when he decides to spring ahead before everyone else.
