Since I installed 9, the time on my phone has been different than the time on the other phones in my family. Anyone else having this issue?

[BrendanKelly10]

Nothing like that so far but I'll keep an eye out for it

Quantify "off"... minutes?? Hours??

Go to Settings>> General>> Date & Time... is Set Automatically on or off? If off - turn on... Is the time zone setting correct and set to a city in the same time zone you'r in? If not - make it so...

Minutes. Like 3 right now. I will double check my settings just seems odd as I thought the time was set by the signal sent out by the cell tower?

My iPhone and my Watch are in sync in regard to the clock. Heck, even my son's iPad is displaying the exact same time right down to the second. But the way, I'm running iOS 9 Dev beta 5.

I'm running iOS 9 beta on my phone and iPad and notice when my alarm goes off its 3 min ahead or behind haha...

I had the same thing on the Developer Beta 5 & GM. Mine was 2 minutes ahead. Now I'm running 9.1 Developer Beta 1 and the clock is on time again. Probably some bug in DP 5 & GM.

Yep. Installed the last public beta and problem resolved. Thanks everyone.

Thank you for letting us know that.

I just installed ios9 in my iPhone 6 and iPad Air; the iPad displays correct time but the iPhone is about 20 seconds fast. No amount of resetting or manual setting will affect the second hand. This will probably cause problems syching with a telescope that needs accurate geo and time information.

Since I installed iOS 9, clock accuracy has diminished by a factor of more than 3000. During the lifetime of iOS 8, clock accuracy improved by a factor of a hundred, going from one or two seconds off to ten milliseconds off. Now, with iOS 9 and 9.0.1, the clock continuously drifts from the correct time, potentially reaching a difference of minutes. The only treatment I've found is restoring the device from a backup, during which the device apparently finally syncs the clock—but that is hardly practical. This can cause problems with all sorts of activities, like two-factor authentication systems, remote control of machinery, etc. It amazes me that nobody tested something so basic.

We did an informal survey at work. Everyone (6 people) with iOS9 on their iPhone and an Apple Watch (running WatchOS1 or 2) had no problems with the time. Everyone else that had iOS9 was off, sometimes by minutes. This is affected 2FA.

Thankfully, this is fixed for me in iOS 9.0.2. So glad to be back to millisecond accuracy.
