I've been traveling and just getting back to this thread. I think some of you missed the point. I have several other vehicles that when you set it to "daylight savings time" "yes", they do it automatically. I thought it was broken. I didn't get the fact that setting that to "yes" doesn't actually do anything. Yes, I get that it's not that hard to change the time, but what's the point of having a setting for DST? If you have to change it manually, why not just change the clock forward or back?

It was the confusion, and the fact that Lexus doesn't seem to be able to do what damn near everyone else figured out that perplexed me. If ya'll dodn't want fancy stuff that makes our life easier, then why are you even driving a Lexus?

The daylight savings works- it is either ON or OFF- ON sets the clock back and OFF sets it ahead--

I guess you missed the point. I have several other clocks that when you set it to daylight savings time, it makes the adjustment automatically.

what he is saying is thay when you have it set to ON it still doesnt change the clock. when it comes spring time you'll have to go in and hit OFF for the clock to adjust.

I have had problems with my RX since I bought it. The computers are set up on the old rules. Besides the clock it also effects the time to destination on the Navigation screen.

The rules for DST changed in 2007 for the first time in more than 20 years. The new changes were enacted by the Energy Policy Act of 2005, which extended the length of DST in the interest of reducing energy consumption. The new rules increased the duration of DST by about one month. DST will now be in effect for 238 days, or about 65% of the year, although Congress retained the right to revert to the prior law should the change prove unpopular or if energy savings are not significant. At present, Daylight Saving Time in the United States

begins at 2:00 a.m. on the second Sunday of March and
ends at 2:00 a.m. on the first Sunday of November


In 2010, DST is from 2:00 a.m. on March 14th until 2:00 a.m. on November 7th.
In 2011, DST is from 2:00 a.m. on March 13th until 2:00 a.m. on November 6th.

Had "automatic" daylight savings mode on my CL500 Benz....it worked automatically until the standard dates were changed- then I had to adjust the clock manually- I think Lexus has it right...it takes all of 30 seconds to turn it on or off- still much quicker than adjusting the clock! ~Cheers!~

All devices that adjust the clock automatically for daylight savings (correctly) are internet enabled so it's always right. Some try to guess it, but things change or some geographic locations are just oddities.

I've seen more than a few clocks that have a daylight savings on/off toggle, one of them is actually the PS3... so it's not all that strange and I was never confused about what it's meaning was... especially given how obvious it is when you turn it on and off.
