Growing up in the Sacramento, California area, it was explained to me that New York was three hours ahead because the sun rose and set earlier there, since they were on the east coast. I knew that San Francisco was a little further west than Sac, so the sun would set a few minutes later there compared to Sac. Therefore, ther must be a few minutes time difference between SF and Sac. For some reason, I thought it was a continual time zone change across the U.S. based on the sun, not broken into time zones like "eastern," "central," "mountain," and "pacific." (Air travel is tough enough as it is, can you imagine if this was the case?)
