How to get alarm time set in default Clock app available in iPhone programatically inside another iphone application. I have found someone say that CFPreferences api can be used but cannot find the exact way of using it to get alarm time from Clock app. Any help is much appreciated.
Looks like there's no straightforward solution to what you're looking for. Regarding CFPreferences API, you'll first need to know how the Clock app stores the alarm information, or even if it does use the Preferences to store the alarm details in the first place. Once you figure this out then only you could use the CFPreferences API to achieve what you want.

I have a requirement where I need to set the internal clock of iPad from inside my code. I did some google on it with no fruitful result. Is it at all possible to do it and if yes, how ?
I'm afraid you can't using official APIs, it's up to the user to change the time on the device. Moreover, the user can't even control when it's set/updated if it's using Apple's time servers.
You can however maintain your own time inside your app using for example this:
https://code.google.com/p/ios-ntp/
If you really need to change the clock, you might have a look on Cydia, this app for instance can change the device's internal clock connecting to custom NTP servers.
Also, some time ago I read this article about how time synchronisation works on iOS that you might find helpful.
It is not possible unless you jailbreak. That is a setting for the user, not for your app.
In my view, No its not possible. Setting system settings is out of the purview of the iPhone developers' SDK. The API's to access such functions are not documented for users to set.
Is it possible to set an alarm & alarm description for the iPhone's alarm clock application WITHIN my application code? So for example, set a 7:00am alarm with a description 'make coffee" in code. So when the user exits my program, if they enter iPhones clock application it will have a 7am alarm set?, any responses will be greatly appreciated. thank you
Nope—your application is sandboxed by the system and cannot access or modify other apps’ data. You can create your own scheduled notifications, however, using the UILocalNotification class; if you Google that, you’ll find plenty of examples of how to create alarm-like alerts that way.
Shouldn't Event Kit serve your purpose?
I've got an app I'm building using Appcelerator Titanium that will be a combination alarm clock/url fetcher. The part I'm having problem with is that I need to be able to set a time for the app to go fetch the url and then perform actions as necessary (in this case alert the user if data that should be entered in a time system has been entered). I also want it to do this every day (or every week day) at the prescribed time, and I want it to not have to be 'launched' every time. I'd rather it come up and run as a service, or at least run as a service when sent to the background. I'm most focused on the iPhone, but I've got a few Android users that would like it as well.
Is it even possible to have an Appcelerator app hooked into the system like that? If so, are there any tutorials or examples? I can't even find an alarm clock example, which scares me a bit.
I think that localNotifications should work for you.
there is a sample in the bg.js file included in the kitchenSink.
It is also helpful to know that all of the keys/properties available to you are documented here in the source code.
This guy has a nice alarm module written for android.

Is there any way that I can develop an application that is running in the background that will detect when a call is being made, start a timer and then alert me at any set time, say before 5 minutes?.
I used to do a lot of iPhone programming but I haven't done any in 6 months. Is there any way to do this now?. Can anyone point me in the right direction?. Thank you.
Look at the documentation for callEventHandler in CoreTelephony. It's not exactly what you want, but read the discussion carefully. You'll be able to use this to do what you want in some cases. If your app is available for full blown background multitasking, then using it might even be reliable.
I was wondering if it was possible to have an "alarm" style app that would run at a certain time? Would the application have to be run and then left open?
I know with multi-tasking on the iPhone 4 a user could open the app and run it in the background. If my original question isn't possible, is it possible to bring an app running in the background back into the foreground after a certain time?
Thank you very much for your help.
Have a look at the new 4.0 feature called Local Notifications. Local and Push Notification Programming Guide
You can use EventKit to put certain alarms. It is however not possible to schedule to launch of your app. You can not bring your app forward like you suggest. You could however send a push notification. The link suggested by Jessedc gives a lot of in-depth information about the use of this.
