Fast Clock!?

There have been many threads with iPad loosing time but I think yours is the first on gaining time. I myself would not be concerned with two minutes over a couple of weeks.

When you sync to your computer it may also sync time. In the general settings under time there is a slider that has set automatically.

I have a wifi/G model. Is yours only a wifi? I know the G has a GPS chip and one can get time via GPS.

I may not use the cellular to sync time. I have not signed up for 3G service. I just checked and my iPad exactly matches my Mac's time even though I have not synced for a week or so.

Yep - I've noticed gain as well. My MacBook Pro went down, so I haven't been able to sync for a few weeks. I have an iPhone 4, an older iPod Touch and an iPad, and they all show different times. The iPhone seems to be on the money, the iPod's a minute out, and the iPad's 3 minutes fast. Not a big thing in the grand scheme of things, but it's a little irritating.

I've also experienced a fast clock. After a month it is now about ten minutes fast. It's been quite a while since I've synced with my computer, that may be it. Since I usually connect to WiFi, I just assumed it would be like my computer and check with the "apple clock". Guess not.

I was having a similar problem with my iPad WiFi+3G, but thought of a recent "Settings" change I had made... which turned out to be the culprit:

I went back into Settings, Cellular Data, and turned Cellular Data back to "On". My clock corrected itself in about 5 seconds... to within 1-second of NNTP.

To be clear: I don't pay for cellular data, and never have. I'm guessing the wifi+3g model gets the correct time from local cell towers passively.

Hope that helps.

Actually, it gets the time from the GPS satellites. The WiFi-only version has no GPS circuitry and the clock syncs to NOTHING. Adding insult to injury, the internal oscillator is not as accurate as the Timex watch that I bought forty years ago!

I just noticed this morning that my iPad is 7 minutes fast. Syncing it made no difference so I changed it manually. What an odd bug.

Yes, my iPad is always 7 minute fast - syncing it never seems to do any good, I just live it it.

Actually, it gets it from the cell towers. GPS is working in 3G models even with cellular turned off, and the correction to the time occurs simultaneously with getting connected to the network.

My iPad time was 7 min fast. I checked the settings and it was on manual, so I switched to automatic.

Now it is 10m fast! I switched back to manual, set the correct time, switched to automatic and AGAIN it's 10 minutes fast.

I do not have the cell plan turned on so I assume it is getting the time from GPS. Could it be getting faulty time information?

I will try putting it on auto, then syncing to see if that makes any difference...
