Problem
Two people are talking long distance on the phone; one is in an East- Coast state of the US, the other is in a West-Coast state of the US. The first asks the other "What time is it?", hears the answer, and says, "That's funny. It's the same time here!"
Show solution
One is in Eastern Oregon (in Mountain time), the other in Western Florida (in Central time), and it's daylight-savings changeover day at 1:30 AM.
