truck lag

 I was 12 years old the first time I went on a long trip in a car. We drove from our home near Philadelphia to Nova Scotia, Canada, stopping at what might have been every "Howard Johnson's" diner along US Route 1 and Interstate 95. The time is one hour later than Philadelphia in Nova Scotia--Atlantic Time--but I don't remember having a problem with it.  Here in California, we're on Pacific Time. Whatever time we're on, I can't seem to stop getting up at 5 am. I didn't know this would happen after a car trip. I don't have a name for it--we've all heard of jet lag, but Budget Rental lag? It's been more than 2 weeks, and I still feel time disoriented. It gets dark before 5, which seems out of place to an easterner, since it's warm. But not because there's more daylight. It seems very late by about 9 ( midnight Eastern Time ) and by 5 am, when it's still quite dark, it seems time to get up.
