Can we change the device time using an application?

Want to know whether i开发者_如何学Gots possible to change the time of the iPhone through an application.. Is that level of dev access granted in iOS4?

My gut feeling is no, but I'm looking for a definitive Yes/No answer if possible.

Note: NSTimeZone class states 'Cocoa does not provide any API to change the time zone of the computer, or of other applications.'

Thanks..
