Friday Commuting

Leave a comment

I am experimenting with blogging from CalTrain. It would be easy on the newer trains with upstairs tables, but the older one’s you have to type in your lap, which slows me down.

My first day back at work went well, and I got everything I needed to do, done. I’ll bring my bag of travel gifts on Monday, I’m not completely unpacked yet!

I have found an answer to an age-old question: Is time travel possible?

The answer is: Yes. Just fly from California to Down Under and back! When we flew out, we left on Saturday afternoon and arrived on Monday morning. Sunday vanished!

On returning, we left at about 2:45 pm Wednesday, and arrived back in CA at 9:40 am Wednesday, several hours before we left.

Naturally, this is not really time-travel in the dimensional sense. It is a result of the International Date Line which we humans have created to help us make sense of the tracking of time around the globe.

In 1884 the line was standardized at 180 degrees longitude in the middle of the Pacific, exactly opposite the Prime Meridian (formerly Greenwich Mean Time, now UTC [Universal Co-ordinated Time] or Zulu). The concept though is much older, being mentioned in a 12th century Talmudic commentary.

This became more important, as travel speeds improved, and for the calculation of Longitude. Of course, the dateline zig-zags around various islands and land masses for convenience. For example, Alaska’s time and date changed when it was sold to the USA. That also involves the Julian and Gregorian calendars.

The first major city to greet each new day is Auckland!

Time Zones are another story. Greenwich Mean Time was established in 1675 for the calculation of Longitude, and was later used to regulate Train timetables. New Zealand was the first nation to adopt a standard time zone on Nov 2, 1868, and most other nations followed suit in the decades that followed.

We’ll talk more about humanity’s calculation of time, but the traIn is nearing SF and I must sign off for now!

Happy Weekend!
