Agreed. My macbook air correctly adjusted to the right time without needing an internet connection, so I don't see why my phone should rely on the carrier.

ATT iP4... Time is -1 hour on 3G, but if I turn off 3G, then the time is correct.
Go figure.

I haven't tried that yet, but I did turn off my automatic time and it went to the correct time then I turned it back on (thinking that it would re-sync) but it didn't.
Well I have power cycled my phone now and it switched to the right time after it connected into the network, but has since fell back an hour.

I woke up in the middle of the night and my Verizon iPhone did fall back an hour. It later corrected itself though.
All cell phones get their time from the local cell tower...
Apple is not to blame here, if you read the comments below you'll see the cell providers are:
"The source of the time displayed on your phone is actually input by a person.
Norrmally, most carriers try to ensure the most accurate time by having the person that sets the clock call one of the atomic clock phone numbers, but in the end, it is still typed in by hand.
This statement is not going to be true forever. Many companies are making changes to the systems that control the cellular network, and, since getting the time-of-day is relatively easy to accomplish now, it won't be long until this function is taken out of the hands of a person.
Edited answer: The person who said I was wong was basically right. CDMA and GSM networks use a GPS clock, but the switch still needs to know what offset to use for the local time. All GPS sats use UTC, not local time. TDMA and AMPS networks still have their time entered by hand."

Post subject: Re: Last execution Time giving wrong time : Post DST issue
Greetings,*
I think you'll have to change the time manually. I've had to do it on several servers and on my windows 5.0 cell phone. As a matter of fact, my cell phone said it changed the clock time, but it didn't and then I found it changed all my calendar events to 1 hr forward. Go figure.*
Good luck. Have a great day."
...maybe I could have found more with different search words, but I think this tells the real story, cell phones get their time from their cell service which is more localized and not maintained/monitored the same way as your ISP for your computer. (I've had clock setting issues when traveling w/laptop, but normally you are in one or two places at most w/laptop and not reliant upon a network of cell towers with more variables).
Calendar events are reliant upon the time being set right in the phone, again, not apple's fault, the cell carrier's problem. This has been an issue since people starting using smart phones (of any brand) for their alarm.

fix is in Time Zone Support
simple fix - turn off Time Zone Support. TZS, which is on by default, sets the time zone that your calendar displays everything in. but there is an error. the good thing is that you can turn it off, which makes all of your appointments come up in LOCAL time, which is really what you want, right?
but first, write down the times of any appointments that you made from your iphone. those times may change when you turn time zone support off. and if the only place where you put it was in your iphone, you may not know what the real appointment time was.

A few minutes before 2am, my Verizon iPhone jumped from 1:57 to 12:57. That lasted for a couple minutes, then it jumped to 3am.
Well, I have serious doubts that someone 'types in' the time for a network. I'm sure they have to configure the local towers to transmit the correct time zone, but that's not the same as typing in 2:00 AM and then waiting to the right second to press enter.
Dates and times aren't stored as hours and minute - it's usually some form of julian date, probably transmitted in UTC. It's up to the local device to correctly convert it to local time.
I note in passing that we're not hearing of any issues with regular phones - just iphones and other smart phones. Anyone have a basic phone show the wrong time?

Man com on Apple! Really! I RUN MY LIFE BY MY IPHONE ALARM CLOCK! I NEVER planed on a back up BEFORE my iPhone when daylight savings time happened why should I NOW? Get this right or I'm leaving for the other phone that has never had this, oh wait, yes they did. Then I'm leaving for my old alarm clock which always changed on its own reliably - oh wait, never mind.
Please. If this is all that is wrong in your life - go to Japan. Think there are bigger problems.

The only thing that would be news worthy would be if a DST went off without a foulup from iOS.
I shutter to think of the effect that Feburary 29th will have.

My GSM iPhone 4 had no issues with the alarms in the Clock App. However, my friend's Verizon iPhone, using a 3rd party alarm app, not only adjusted the clock 1 hour, but also added an hour to the alarm's time.

I don't use my iPhone 4 (AT&T) for an alarm, but I did not notice any issues with it today.
However, my new iPad 2 (Wifi-only) is showing a minor bug in the Calendar app: https://forums.macrumors.com/threads/1116373/

This is bizarre: My AT&T iPhone 3G displayed the correct time this morning, however as I go to bed, it is an hour behind. I went to the Date/Time settings and made sure that it was set to automatically adjust the time. When I turned off the auto adjust, it displayed the correct time for my time zone. When I turn the auto adjust back on, the clock goes back an hour. 
Both mine and my wife's iPhone changed to DST ok, however, at 8:30 Sunday night I tried to set my alarm for 2:50 AM and it wouldn't take. I set the spinners for 2:50 AM and selected "save", but the alarm list reverted that time to 1:50 AM. Happened on both phones (3G and 3GS). At 5 AM Monday I am able to set it for 2:50 AM. Weird. Just a glitch with Sunday I guess
Strange that Apple can't fix this..
My wife's iphone went *back* ( not forward - it went forward as expected yesterday ) an hour this morning ( Monday !), my Nokia smartphone is fine.. and yes, we are on the same network. I doubt this is an issue due to operator time, its the phone itself.
