Your questions: Is there a list of the time zones and daylight saving time changes in Windows?

A question came in via email, IM and phone today, so thought that it would be beneficial to post it here…



“Is there a list of the time zones [and daylight saving time/ summer time] changes in Windows?”


Why, yes, there is a list of all changes included in KB article 933360, “August 2007 cumulative time zone update for Microsoft Windows operating systems,” that notes that the following changes have been made since the previous Windows cumulative time zone update in February (KB article 931836) :



  • Caucasus Standard Time:  Changes display name to Caucasus Standard Time as cities in the previous display name have separate time zones, and removes DST settings. 

  • Armenian Standard Time:  Creates a new time zone for Armenia to better align with different DST changes in the Caucasus region. 

  • New Zealand Standard Time:  Adjusts DST start dates and end dates according to changes signed in to law after the prior cumulative time zone update was created (February 2007).

  • GTB Standard Time:  Corrects the display name for GTB Standard Time on Windows Server 2003 SP2 to include Bucharest. 

  • Jordan Standard Time:  Adjusts DST start times, end times, and dates according to changes signed in to law after the prior cumulative time zone update was created (February 2007). 

A list of the display names and GMT offsets are noted here for your review…

MTV loses its Urge, enthusiastic for Rhapsody

First off, if you’re in Washington State, check to see if it’s time to go and vote in your county primary elections.

Now, on to the news as I break early for lunch and out to vote.

MTV Networks will drop its Urge digital music offering, partnering now with Real Networks’ Rhapsody music service (and backed by Verizon Wireless).

ExtremeTech reports

“the expected partnership [between MTV and Real] will result in a new company, dubbed Rhapsody America. It is intended to create a single, digital platform for PCs, portable music devices and mobile phones, executives said during a conference call.”

It will be interesting to see what comes of the discussions between the companies and how MTV’s Urge digital music service as music on Urge music should “be available on Windows Media until further notice,” according to Van Toffler, president of MTV Networks’ Music Group. Urge customers can now can use their accounts to log on to Rhapsody.

I like Rhapsody’s subscription service. And I am considering the move to the Zune Pass subscription, which also offers and ‘all you can eat’ song library via Zune Marketplace. I never got the Urge.

Online subscription packages like Rhapsody and Zune has certainly changed how I buy music… and I found that I purchase more CDs at a rate that parallels when I was more involved in the industry. As noted, subscription packages allow me to “try before I buy” legally thus exposing me to more musical talent than I get via radio today.  For many artists, I prefer to have higher-quality digital files available, ‘though the quality of subscription music is fine for working out or general travel via mass transit… but I do notice the difference sometimes listening in the car and particularly at home.  

BTW, my Rhapsody subscription music folder is now about on par with the folder of my ripped CDs that I own (‘though digitized at a high bit rate) as most subscription tracks are encoded at a lower rate (128 kbps) than I digitize my CDs.

New Apple iMac cabling, PC cable messes and solutions, part two

A number of people have left some great comments on the blog re: my post on how Apple compares the simplicity of their iMac vs. the cable mess associated with a Windows PC.

And again, the standard disclaimer: I own PCs, Macs and other various computer systems, some off and some on the home network. 😉 

A quick note on a single cable PC: there are solutions available. My point was that there are better comparisons (certainly not in Apple’s interest) that offer a similar minimal cable configurations, such as the pricey Dell XPS M2010 (which Dell says is a notebook PC), more affordable HP’s TouchSmart IQ770 (lots of discounts in the Sunday sales circulars this weekend) and the range of Sony all-in-one PCs.

HPIQ770Of interest: HP has an interactive 360 view (in Flash) on their web site. I’m surprised that they (as does Dell and also Sony, with a 360 product tour here) haven’t taken the same approach as Apple in their single cord solution, and just highlight a single power cord connecting the PC.

And note on our new home PC set up: we have three cables coming out of the back of our HP Slimline PC: the power, the monitor and USB camera cable. (I have an HP monitor which doesn’t offer a set of USB ports on it as does my Dell monitor at the office, integrated into the bezel.)

Although initially reluctant, I disconnected the Ethernet cable and used the integrated wireless 802.11G to access our home network with little noticed hit to the network performance, as the laser printers are on our network. (Note that I do have a scanner on the desktop but that is disconnected as we clean up the home office this weekend.)

Wireless Entertainment Desktop 7000The system is complete with a Wireless Entertainment Desktop 7000. I’m thinking about upgrading to the new Wireless Entertainment Desktop 8000 as this Bluetooth mouse and backlit keyboard set has four USB Ports.

If anything, I’m reminded that it’s so much more satisfying to have a clean desk. And the fewer the cables the better.

That and thinking we should look at one of these new iMacs or PC all-in-ones for our home office, v-next. 😉

Xbox 360 repairs are complete: our first unit comes home

It’s returned home.


Our Xbox 360 that suffered from a severe case of the dreaded three red flashing lights arrived on Friday and is now up and running.


Well, not exactly the same Xbox 360: we were informed that the unit we received was a replacement unit, but it’s in fine shape. (Let’s hope that this one doesn’t scratch game discs.)  All told, we waited about five weeks from the first call to the Customer Service centre to this week when UPS showed up with a plain white box.


Not that anyone missed the gaming system today: it was a gorgeous day with baseball, bike rides and much more filling the schedule until late this evening. We had just one session of Dance Dance Revolution on Friday before the kids headed to bed.


What else was in the box: instructions included with the unit were helpful, and it was nice to receive a letter from the Xbox team (in English and Spanish, thank you) apologizing for the issue.  And the bonus of a free month of Xbox Live that many people called out in mail to me was included in the return shipment.


Which is a wash as the unit was out of service for just over a month.


Update on another unexpected bonus: as you may have seen in an earlier post, our older Xbox 360 just went south (a month after the standard one year warranty expired). Good news is that I purchased with a credit card that automatically extended the standard manufacturer’s warranty by one year. That means the $99 repair fee should be covered… a small victory and good reason to keep that plastic.  So check your card agreements and see if you’re covered (some exclusions always apply).


Case in point: I saw recently that Costco extends the manufacturer’s warranty on new computers and televisions to two years from date of purchase. But Costco does not, it seems, extend this offer to video game consoles.

The Apple iMac vs. Windows PC cable mess: what’s real?

There is an amusing image on Apple’s web site that compares the cable mess that apparently doesn’t burden the new Apple imac as compared with the Dell XPS 410.


iMac vs. Dell


OK, for a second, dispell belief.


The Mac has a single cable coming from it, assuming that there is no wired Ethernet connection or USB peripherals, such as a printer. (Yes, I know… wireless network connections are available, but I also have a wireless 802.11G on our new HP Slimline PC and notebooks, so let’s just assume an Apples to apples comparson. 😉 That’s two cables. It has a built-in camera, my PCs do not (although more popular these days on many notebook and mobile PCs). The iMac does not have a series of memory card slots to allow me to move files from SD cards, so add a cable for the multi-card adapter.


That’s three additional cables. And I’m not sure what that thing is on top of the Dell.


Granted, a lot of the cable savings on the iMac come from the daisy-chained mouse and keyboard, integrated camera and speakers. I have some of the same savings as I have a Microsoft Wireless Laser Desktop 6000 installed and a Microsoft LifeCam VX-3000. And if you’ve read previous posts, you’ll know that I have nothing against the Mac or Apple, having spent the bulk of my career using Macs (1984 through 1998) as well as PCs (really post Windows 95). 


If you took Mr. Peabody and Sherman’s WayBack machine to 2003, you’ll see a PC prototype, co-developed with HP and codenamed “Athens,” that mergedvoice, video and text messaging. (Also see this story on the Athens PC on CNET News and this previous post.)


Look familiar? 


Heck, Athens even had an integrated phone, something I would like for my desk as I have a home office Polycom desk phone at home. Sure, it would be nice to have the camera in the LCD monitor bezel, but the one on Athens was adjustable, which is what I like about the LifeCam on my PC today: I can move it to suit my needs.Sony VAIO VGC-LS25E PC


Having said all that, where are the cool PCs?


Some of the new crop of Windows Vista PCs are shown on the Windows Marketplace site here, including the Dell XPS M2010, HP’s TouchSmart IQ770 and the Sony VAIO VGC-LS25E (as well as the range of Sony all-in-one PCs). Design-wise and of these PCs, the HP and the Sony all-in-one VAIO are on the short list for my new office computer, given recent price drops.


And fewer cables.


If you’re looking at comparable cable connections, then I’d look more at the Mac mini or the Mac Pro tower. Then I expect to see a similar amount of spaghetti wire behind the hardware. 


An additional thought: a Dell XPS 410 is less than $1,100 for a 20-inch Flat Panel Monitor, Intel Core 2 Duo Processor E6600 (4MB L2 Cache,2.4GHz,1066 FSB), 2GB of memory and a 320GB5 Serial ATA hard drive. For the same price (actually, $100 more) you get an iMac with a 20″ 2.0GHz Intel Core 2 Duo, half the memory (1GB), and a smaller hard drive (250GB hard drive).


A close to comparable iMac is almost 50% more: the next model up is $1,499 for a 2.4GHz Intel Core 2 Duo, still 1GB of memory and a 320GB hard drive. There is a more robust graphics card in the 256MB memory ATI Radeon HD 2600 PRO.


For that amount, the HP and Sony models below are comparably priced after some of the current discounts I’ve seen.
