My dream world is we apply time zone logic to every other unit of measurement.

1 metre can be 100cm or 200cm depending on the season and your location

My nightmare world would be one where we apply "everything else" logic to time.

1 kilosecond: about 17 minutes

1 megasecond: about 12 days

1 gigasecond: about 32 years

"Oh man, it's been a hot megasecond since we last spoke!" Said everyone, in my worst nightmares.

12 oz of alcohol would obviously be larger in the winter the closer you get to the poles. I think I like this idea.
