Hundreds of Time ZonesTwo hundred years ago, America had hundreds of time zones. As odd as that sounds, it makes sense since noon was when the sun was at its zenith in a given location. High noon in Boston might be seven minutes earlier than New York which might be three minutes earlier than Philadelphia. Having hundreds of time zones wasn't an issue since these cities weren't connected until the railroads needed to run on time schedules.
PS – For the record, it's daylight saving time, not daylight savings time. We're saving daylight by moving it to the end of the day. We're not saving daylight like money in a savings account. :^D
