With computers we could avoid that problem today...but results in the impossible-to-predict business hours. the 9-5 workday at least makes it easy to know when someone will be home in the bank or office.
I think it wouldn't really be that hard for everybody to just use GMT. Here in CA I would get up about 1400, be at work by maybe 1500-1530, leave work around 0100, and go to bed around 0700. Around me, banks would be open 1700-0100. If I happened to live next to a current time-zone line, banks on the other side might choose to be open 1600-0000. Everybody's hours are posted online anyways.

It's not like people can't deal with the modular arithmetic, we all do it with noon every day.

I would call 2000 'noon'. People across the neighboring timelines would call 1900 or 2100 'noon'. People in Australia call December 'Summer' and nobody gets confused.

No such thing. It's called the "Southwest Path". Yes, commuters are among the _multiple_ types of users, but it is a "Shared-use path":




On surface roads, we (cyclists) expect faster users (motor vehicle drivers) to share the facility with us in a safe manner. Likewise, on shared-use paths, slower users (pedestrians, including joggers/runners) expect us (cyclists) to share the facility with them in a safe manner.

And for much of the planet's population, the date would change in the middle of one's waking hours and/or business day. Run that notion by the couple billion people so affected, let's see how it floats with them....

yer right I forgot about date. CA for instance would change date at 4pm. Why does reality gotta be so annoying?!

Reminds me how I wish when I was in college or grad school I had taken the opportunity to try out a 28hr X 6day week.

Well that only makes sense, shouldn't you celebrate the new year when the - when the - well shoot, it's really pretty arbitrary, isn't? When the Earth breaks the plane of the end zone and makes a touchdown into the new year, right? Or when your time zone crosses the plane? That would make the new year travel both ways around the planet and it would happen every 365.256 days. The Earth takes about 3 and a half minutes to travel its own length so the whole thing wouldn't take very long.

lol I was in london for 2000, they planned a 'wall of fire' to have firecrackers along the Thames fire off exactly as the new 'millenium' line sped down the river (not using your whole-planet-break-the-plane definition). It was a sputtering disappointment done in half a second.

My mistake.

I certainly never suggested that the path was exclusively for commuters, but it also wasn't really important to my point, which is that the Madison Ninja Joggers are practically invisible at night, so be careful.

^^^^ Hmm, somebody's gonna have to talk to Tom Mohr about that "Commuter Path" phrase, that was phased out years ago at the request of neighbors who most certainly DON'T use it to commute.

Aha. I was kinda wondering about that. I do remember the old signs.

this is what I was hoping for in an answer.... not a discussion of the validity or lack thereof for DST.

But that's the Bike Forums way! We drift all over the place.

That said, generate at sunrise/sunset table from the link I provided in post 18 above and tape it to your refrigerator. You'll have to add an hour to each time during Day Light Saving but at least you'll know when the sun rises and sets for everyday of the year for your locale.

And, just to drift a bit further out of the lane, there are interesting things that happen around the solstice. Many people think that the sunrise and sunset are at earliest on the winter solstice as well as thinking that the sunrise and sunset at the latest on the summer solstice. Neither is true. The summer and winter solstice are the period of longest sunlight and shortest sunlight per day, respectively, but that's only the duration of the light available. For summer the earliest sunrise occurs around June 15th (for Denver the sun rises at 0431 from June 11 to June 18) and the latest sunset occurs around June 25 (Denver: 1932 from June 22 to July 3). See chart below

Summer solstice by Stuart Black, on Flickr

For winter, the difference is between earliest sunset and earliest sunrise is about a month apart and inverted. The earliest sunset occurs around December 5 (Denver: 1635 December 5 to December 10). The sunrise time keeps going later and later until about Jan 5 (Denver: 0722, Jan 5). The days get longer after the solstice but it gets longer in the afternoon and shorter in the morning. See chart

Winter solstice by Stuart Black, on Flickr

The times and duration will vary depending on latitude.

Here's the chart I created for explanations - a little confusing because Excel charts with time in reverse, so a day proceeds from top to bottom.

We should all be thankful that we live in a time when we can manipulate time itself to conform to our wishes.
