Another p.i.t.a. tomorrow morning

If you really want to go down the rabbit hole, study The Equation of Time. This relates astronomical time vs civil time.

Civil time is set by a standard of 24hours a day but that's not quite correct for various reasons way too deep to get into here (mostly related to the Earth's location in it's orbit and the angle of the earth's rotational axis).  Astronomical time is time kept by the sun, like high noon.  Actually the equation of time relates astronomical time to mean solar time but mean solar and civil time are pretty close.

This becomes important for astronomical navigation and other things that I have had to deal with on occasion. 

Here's a graph of the Equation of Time for 2014

Here's a graph of the major factors going into it.

A little light reading on the subject.

Maybe not, but they have to constantly calculate the time difference when doing business with the English.

Nobody says you have to change your clocks either. It's just when you show up at the machinery dealer to pick up that critical part an hour after they close, or you're late for work by an hour because you did the conversion wrong in your head, that it matters.

I set my clocks right and still show up at the sometimes show up at the wrong times anyway!

Time to resurrect the argument about DST!

I haven't heard, are we still supposed to change our clocks tonight or did they decide to make it permanent?

Been waiting for this weekend to ask a dumb question. Preface, I live in the middle of a time zone. I have to drive 6-8 hours to enter eastern or rocky mountain time, needless to say it's not something we deal with locally...

For the people who live right on a time zone change... I.E. central Tennessee - how big of a PITA is it to keep track? Do businesses close to the time line open an hour earlier or stay open an hour later to catch the people who live/work opposite?

It just hit me a while back, a married couple living close to the line, one commutes.... who's watch do you go by?

County I grew up in was the western edge of Eastern Time Zone. So the county line was Central Time. Not really a big deal, businesses didn't do anything different, sometimes if you were making plans and the other person was Central Time one of you would as "Are we meeting at 9 YOUR time or 9 MY time?" But we were used to it, so not a big deal.

China solves that by having one time zone for the whole country. I guess you get used to going to work at 04:00 while in Beijing it’s 07:00.

I’m on the eastern edge of the time zone and would be happy to just go on AST and stay there, essentially EDT all year.

our time changed last night. Article in little flyer paper warning to watch out for the wildlife since the time changed. I did not know they changed their clocks also. but at nearly 74 years old this time change is about as hard on a person as any hangover i ever had.

...I  personally, have always  loathed  this BS business of daylight saving time....

For the last few months ..have been full on with extensive farm flood damage  restoration work...on a 20 ton Volvo Excavator...  

I generally start at 9 o'clock ''proper time '' instead of 8  o'clock 'bureau  time ',,,and finish at 5 o'clock ''proper time''.....depending on the Farm's staff obligations..

This causes little comment..I just say   at now over 80 yrs , I call the shots on my starting time...no one objects  !!!

It used to really wind me up ,back in the seventies when our left wing lunatics' changed the clocks in early spring... ...I had to go to bed in the daylight  ...so as to get sleep for the next day . arising around 4.00 am to work as a Forestry contractor...Bloody ludacris situation....

My wife changes most of the clocks a week early to “adjust” to the change, she then spends a whole week continuing on as she had and just adjusting for the incorrect clock. I would argue about it, but I might as well discuss it with the refrigerator, so I just wear a watch and roll my eyes.

Doesn't bother me much except for the fact that it gets dark at 4:30 pm in the middle of winter. On DST at least we'd have some daylight after 5. Plus I like the long summer evenings with light until 10pm.

[acem]

It don't bother me much.  Sun comes up and goes down.  That regulates my day more than a clock.

Sometimes when I get really busy (planting, hay, harvest) I loose track of what day it is and go to town or something and everything is closed because it's the weekend...

So we stayed at a KOA in Horse Cave KY this summer - baseball games were in Elizabethtown, KY.  I could figure out what was going on when I looked at a clock on the wall and then realized we were right on the line.  Made it nice leaving ball game and going to Nashville to gain an hour!

I personally hate this fall time change because by the time I get home from work, I don’t have much daylight for farm work (1-1/2 hrs).  Chisel plowing last week stopped around 6:30.  Subsoiler on now and I have until 5:30 and it is dark so not much time.

As someone who regularly crossed multiple time zones almost daily I have to laugh at those who think a one hour change is a big deal. I overheard a conversation last night in a restaurant where a woman stated that changing the clocks caused her jet lag just like when she flies to Florida. Huh? Florida is the same zone as NH!  

There was a study quoted many years ago that was done on Pan Am pilots who flew the South America routes v The Europe and Asia routes that stated that the N-S pilots who crossed fewer time zones had fewer health problems than those who flew the E-W routes.  Maybe I can find that study.

the early morning light is depressing to me because i have to go to office job during day.   When it was dark at 530-6am i felt like i was getting ahead,  and then i had light in the evening to do some chores,   Now sun is already coming up at 530am and by the time i get out of here its going down or already down.   Everything on the farm now happens after dark. The abrupt change doesnt bother me so much as the fact that I cant change my work schedule to match the light availability.
