SUMMARY

The start date for Daylight Saving Time (DST) changed in 2007 due to the Energy Policy Act of 2005, which mandated that DST begins on the second Sunday in March and ends on the first Sunday in November. This adjustment aims to save energy by utilizing more daylight in the evenings. However, the change has sparked debate over its effectiveness, with many arguing that it disrupts biological rhythms and does not yield significant energy savings. Critics suggest that the shift causes more harm than good, particularly for those who wake up early in darkness.

PREREQUISITES
  • Understanding of Daylight Saving Time (DST) principles
  • Familiarity with the Energy Policy Act of 2005
  • Knowledge of the impact of time changes on human biology
  • Awareness of energy consumption patterns
NEXT STEPS
  • Research the historical context of Daylight Saving Time changes
  • Explore the effects of DST on energy consumption and savings
  • Investigate the biological impacts of time changes on human health
  • Examine software and systems updates related to DST adjustments
USEFUL FOR

This discussion is beneficial for policymakers, energy analysts, health professionals, and anyone interested in the implications of Daylight Saving Time on society and individual well-being.

I am wondering how my vcr updated the time...

Elves, gremlins, goblins, kobalts, . . . take your pick. :biggrin:

Perhaps it received a signal or software update (assuming a programmable digital VCR) from your cable provider? If it's new, then perhaps it has appropriate software?

It is a few years old (maybe 2 or 3), and quite basic (I don't think there is anything "digital" about it). Either way I am glad that someone changed it, I was just going to wait it out until April :smile:

My laptop has XP and I am sure I didn't advance the time before I down loaded the 'patch'. I let the patch make the time change - but then it made another time change. I changed the time back to the correct time (new DST), and the OS changed the time again. So I disabled the DST automatic update and set the clock back 1 hr to the new DST. This morning, I tried the reverse. I set the clock back 1 hr to normal time and then activated the automatic DST. Now the XP has the correct time.
Wait until the "official" DST change date and be prepared to wrestle that alligator again! :smile: I wish we would just pick a time standard and live with it. If local school districts feel the need to adjust their schedules, etc, let them deal with it. Living in Maine and being appended to the Eastern Zone (while we are surrounded by provinces in the Maritime Zone) stinks! In mid-winter, it is night-dark by late afternoon while usable light is assigned to early mornings. Cabin fever is a big influence here during winter, especially for working people who have to drive home in pitch blackness and have no light after-school time with their kids.

I think that would be so much easier. Just let local school districts set their hours to whatever makes sense locally and for the safety of the kids rather than sticking everyone on some arbitrary time shift. Heck, in the winter, I'd rather start much later so it's daylight in the morning when you wake up, and then you just work your 8 or whatever number hours. Either way, you're coming home in the dark, so who cares how long it's been dark, but then you can at least wake up in daylight so you're not getting up in the dark and returning home in the dark and never seeing the sun all day. To me, having the sun up is more important for waking up in the morning than to stay up at night.

That is my reasoning, too. It is much more important for people to see the sun during their day/commute/whatever so that they can establish a connection between the world and their inner clocks. It is far less important to shift hours of commerce back and forth by an hour or so, and that is an anachronism that should be eliminated. It is not as if we are a culture that is dependent on local church-bells and town criers to unify our sense of time. We can all be well-aware of the time (GMT, local time, etc) and also be aware that our employers/schools, etc would like us to show up earlier or later depending on where you are in each time zone and where you are in the country if your business is engaged in commerce across the country or the world.

This is not far removed from the notion that we must have an electoral college in the US. An idea that arose from the practicalities of elections and the reporting of their results. If the congressional delegates traveled back home to their districts, it might take weeks for them to return to Washington with the electoral tallies. Nowadays, popular elections are not only do-able, but should be preferred to eliminate some of the corruption that accompanies the leverages enabled by the electoral college. Popular elections will not be afforded to us as long as the crooks who benefit from the corruption inherent in the present system are weeded out.

My macs receive automatic updates for everything. I wasn't sure if one of my earlier macs would get updated so I set it manually and now its 2 hours ahead of everything else.

In a sort of Runic rhyme,
To the tintinnabulation that so musically wells,
From the bells, bells, bells.
