I had to manually fix my clock today. Since I have XM, shouldn't the day light saving time adjust automatically??

 

theres an auto daylight option under clock settings on the tech. i didnt have this set so it didnt change. I'll let you know how it goes in 6 months

This has been discussed in various threads all over Acurazine. Here is one of my answers that will help you understand what the tech package does. Turn off the Auto DST and go manual.


GPS satellites have an internal atomic clock that that was synchronized to Coordinated Universal Time (UCT), which is also commonly referred to by its old name Greenwich Mean Time (GMT), back in 1980. The GPS satellite constellation runs on "GPS time" which is not continually synchronized to current UCT. The difference is that the GPS time signal is not corrected for leap seconds, etc., and over the years, GPS time diverges from UCT. However, the GPS signal includes a correction factor for the original 1980 synch, so that GPS receivers, such as a car navigation system, can take GPS time, use the correction factor to calculate UCT, and then use your position coordinates to set a local time. The point is that the GPS signal contains the baseline time data, and the GPS RECEIVER makes the calculations to convert to local time.

So our car GPS receivers are programmed for the traditional US April and October daylight savings time, and would need a software/firmware patch.

There is some talk about a patch in the works over on the TL side

This is a minor issue to be sure, but manually changing the time on a luxury car that was designed to do it all for you really is unacceptable. The amount of work involved to program the car for the new rules is so trivial. I found articles on the internet dating back to 2005 which mention the 2007 change. So if the world knew this was coming in 2005, why couldn't Acura include a fix in a car that wasn't released until mid 2006?

 

I agree, but who knows what kinds of qualifications they have to go through?

While I don't know of any, you wonder, if in all its wisdom, the Government has "safety of opertions" like certs, for the car makers. Change the software, and you have to do extensive testing to make sure your changes do not affect other operations unintentionally that might affect safety. Imagine the liability if the time change affected some other system the driver relied upon, like the navigation system calculations.

 

The user accessible clock would never be tied into any function related to the operation of the vehicle. THAT would be too dangerous. You know how many people's VCRs flash "12:00" all the time? It's just an annoyance that a $37k car can't figure this out on its own, but my crappy $25 sharper image atomic alarm clock did it just fine.

 

You know, you two guys...here ya go again (two trusted opinions over my head)... Can a regular person keep up with you? When the two of you get at it... well, can you put it in layman's terms?...

Can I reset the clock on the tech model?

 

since the time change is early this year, it seems the nav system didn't know about it. Mine did not change, although it's supposed to be auto. I looked in the manual for help, but there's nothing I found. I believe this early change is not state wide though. am I wrong?

 

I do not disagree with you.

I was just wondering if anyone knew if automotive software has to go through any kind of certification testing, so that even if a small change is made, and the change process becomes potentially lengthy and expensive is enough for Honda to just say, too expensive, deal with it in the owners manual and tell them to turn off Auto DST and go with manual time changes.

As you can tell, I am wordy, and that wordiness serves to confuse what I mean. Sorry.

 

Absolutely. I do not have the navigtation manual handy, but I think you just go into set up, and look for clock settings, or something like that, and Auto DST is a choice. It should be default to On, but select Off, so you don't have a problem 3 weeks from now (because Auto DST is programmed to change in April), and then manually reset the hour.

 

thanks chase2, now i understand (i think). if i don't turn off the AST, the computer in my RDX will simply add an hour & then i would have to fixed it again. otherwise, my time is being sync with the satellite every day. after April, I can turn the AST back on & I should be good for the next change.

 

Acutally not, because Congress also changed DST for the fall to early November. It is crazy! Unless Honda pushes out a patch, I would not bother to turn Auto DST back on.

Besides, in the authorization bill, there is also money to conduct a study to see if the time change was worthwhile. If not, then they just might change it back to the way it was. If they change it again, they might as well synch with the EU so at least half the world will work better as far as time changes go. Then of course, there is always Arizona....

 

I posted this on the regular discussion section, but yea, Acura is planning a "patch" (at no cost to us) I understand in the form of a DVD. There is no estimate on ther date for this patch yet. Not sure, but I wouldn't be surprised if they end up sending the patch the the dealer and call it a "recall." I'm sure Acura doesn't want us to mess with changing our own DVD (the hand book frowns on this anyway). This in fact, will be a good marketing feature for them, as we'll have to bring our car in for service. I know, they didn't plan this time change thing, but it might work in thier favor...

Service manager: "Uh...Mr. Jones, while patching your car's nav, I took the liberty to check your fluids for you...I put new wipers as they were a bit worn."

Mr Jones: "Oh thankyou so much" LOL

 

OMG You all have to be kidding me. First off the car is programmed with tradition time changes has nothing to do with your navi, if its a tech package ect. second off the time change to the new format is a test to see if electricity consumption will be less. Get over yourselves and press the three buttons it takes to change the clock. I know you all have problems using your brain when you buy a car nowadays and need it to think for you.

 

Relax. Just because you don't mind changing the clock manually it doesn't give you the right to bitch because some of us like the automatic feature. It was nice last Fall to not have to manually adjust the the clock. I wish all clocks were like this. Too bad I only got to enjoy it once. Best option is to just get rid of DS.

 

I agree it's so easy to change the clock manually but some other reasons they may have decided not to do it:

The government may also decide to go back to the original DST at some point if they deem this was just stupid so I would think you're better off chaning the time manually for now until they make up thier minds. And the changes were also made for things such as farmers tending thier crops and other things most of us do not care to think about.

And I also don't think anyone bothered to consider how much work it has caused many people such as your friendly I.T. departments and the many companies involved within the technology field.

 

personally. I hope the new DS changes are here to stay. The season cycles are changing as always, as does all life, timeto change with it. Bring it on...and I'll take that patch please.

 

I'm sure there is plenty of testing, but we're not talking military grade here. The bigger issue is that since car design lead times are so long (3-4 years) and production scales are so large (40k per year for RDX, 500k per year for something like a Camry), the automakers have to be very conservative and deliberate in what gets produced. It's not as easy to upgrade a car as it is for Microsoft to send out a software patch (every tuesday, right?)
