Title: Is it darker?
Post by: Bonk on October 25, 2009, 06:20:29 am
I'd swear it was December 21st by the light these days, street lights on until 8am, back on again at 5:30pm... Sometimes I think I'm just feeling the effects of that recent change to daylight savings time (that was supposed to save money but of course will not). But that does not make sense, DST is to match nature not the reverse... It definitely seems darker to me, all the time. The sun is already about 30 degrees above the horizon at high noon in October. Where will it be in December? Has the precession of the earth's rotational axis changed? I begin to think so. I wonder if I can find a graph of sunrise and sunset times at this latitude for the last 30 years? Maybe my eyes are just getting old?

What recent change (http://www.timetemperature.com/tzca/daylight_saving_time_canada.shtml)?

Oh I dunno, wasn't there a change recently to DST to supposedly save energy in the last year or two? Something Bush started?

LOL...Bush is responsible for how Canadians set their clocks?!

That is not funny. To mis-attribute my question as a statement in a tone that I would not make according to our own site policy. You're reaching way too far, and out of bounds. Not everything is about politics, and outside H&S it explicitly IS NOT. Back to your cage!  :whip: ;)

Whatever... This thread is about daylight.

Well ultimately I guess we have some New Zealand entomologist by the name of George Vernon Hudson to thank/blame. According to wikipedia he came up with the bright idea in 1895.

But no, provincial governments determine what time standard we follow here, and I suppose if we decide to follow a "standard" we might as well use the current version of it. It is the "version" (if you will) of DST that has changed recently - there was even a windows update that corresponded to it... and I'm pretty sure that Bush played a role in the adoption of this modification to the standard. (with no implication other than to place it in time)

I guess I'll have to find the story now, I was hoping somebody here would remember.

Found some discussions, looks like it was a few years ago (man time flies).

Daylight savings time, IIRC, was implemented with farmers in mind. It allows for a longer work day by shifting some early morning light to the evenings. Recently, in a goal to save energy, it has been extended as far as possible. I think Carter tried to put us on DST year round, for further energy savings, but it was too dark in the mornings and some children were run down on their way to school and it was stopped.

Not sure about DST in Canada, but it does seem to be darker, earlier, at least here in the middle of nowhere, compared to other years.

Right now it's 3:30, and it looks almost like dusk. Then again, we have had a lot of cloud coverage lately.

IIRC also, it was started to help farmers out.  But with havesters that light the night like daytime and 24 hour combining I don't see the need anymore.  As for energy savings, I don't see where it would come in so much.  Buisnesses run lights the whole time they are open, daytime or not so no savings there.  Maybe alittle for homes, but earlier morning use would be longer, and at dusk most people run lights to see better anyway so not so much a savings.  I would love to see it all dropped.

As for darker, haven't noticed it being darker for me here in the middle of the US.

I believe Daylight savings time had more to do with German bombing runs during WW I.  Edit:  Yes I know it was started by Franklin but I'm talking about modern day use.

The darkness is sent forth to herald the approaching end of the Mayan calender, and with it the apocalypse.
