fixing your clock

The https://time.is is synchronized to the atomic clock in Colorado, and is certainly good to the second.

Yes, that's all true. But I don't think that that level of accuracy is used in the communication to cell phones.

I think cell phones are only accurate to the nearest minute. I could be wrong.

Edit. Oops! I just checked my cell phone against my watch (which receives signals from the atomic clock in Colorado) and it is indeed accurate to the nearest second. Somehow I got something mixed up!
