I would not be so confident that people know there own timezone... I know what it is right now, yes, but at some times of the year I wouldn't be sure what it would be next week. Have the clocks gone +1 or -1? Is that this weekend or next that daylight is saved? It might have saved daylight, but on at least one occasion it cost me breakfast And summertime in Europe happens/used to happen/ on a different weekend than in the uk, so if you travel 40 km on the wrong week the time difference can jump between 0-2 hours. That issue with the wrong constant reminds me of a time I was debugging some astronomical code that seemed to show that it took light 9 minutes to reach us, rather than the expected 8. I was beginning to suspect an error in my constants. I rigorously checked the degrees/radians conversion factor at least twenty times, and every decimal digit was correct. Eventually I realized it was a non-decimal digit that was wrong: 157.xxx instead of 57.xxx It is so easy to read what you expect to see. Surely it is time that technology only allowed constants to be copied, rather than typed in??? Stephen Lewkowicz (G1CMZ) https://my.numworks.com/python/steveg1cmz |
