FAQ

My iPhone™ is only off by 4 seconds; why do I need this silly app?
You don't. But some of us think such an error is insanely huge for a 21st century computer. It's just not right.

It doesn't properly work on the iPad
Please upgrade to version 1.3 or later.

The seconds have disappeared!
Tap the seconds window. That cycles between displaying the seconds with tenths, the seconds only and nothing at all. That's convenient if you find the blinking seconds annoying. But it's confusing if you don't know that. Now you do.

What does a "?" in the upper right mean?
That Emerald Time can't contact any servers. Make sure you really have internet connectivity. Be patient. Or tap the lights to force another retry. Sometimes it takes several tries.

All the servers in the list are red or gray like the picture above.
See previous answer.

What do the colors mean in the table of stats?

What are those funny server names?
Emerald Time uses servers from the NTP Pool Project. The addresses you see are not real; they just redirect (more or less at random) to the real servers. You will not get the same real server each time. This is good.

But what if I somehow get connected to a really remote server on another continent?
It will probably work just fine. An NTP server half way around the world seems to be able to supply a more accurate time than the cell phone tower a mile away. But Emerald Time picks the best of the servers it tries anyway, so it's not likely that a really distant one will be picked.

My iPhone has GPS built in. Doesn't that have a really accurate clock?
It sure does, and it's accurate to a few nanoseconds (if it wasn't it wouldn't work). In fact, GPS receivers are very often used as the reference standard for NTP servers. But some versions of iOS do not use the GPS time information. And of course, some devices don't have GPS.

I ran Emerald Time and it got a good time setting. But when I quit the device's clock went back to what it was before.
Yeah, that's how it works. Setting the system clock requires root privileges which are granted only to Apple's own apps. This is probably a good thing in general; you really don't want random programs messing with your system.

What's that misshaped "o" at the head of the middle column?
That's the Greek letter sigma (σ) which is conventionally used to represent a standard deviation.

I'm confused about how to set "Disable Auto-Lock"...
Yes, it's a little confusing. iOS's system-wide option is called "Auto-Lock"; when it's enabled (set to something other than "Never") the screen blanks after a while. This is often not the behavior you want in an app like Emerald Time so we have an option to disable the system-wide feature for our app only. Thus when our option "Disable Auto-Lock" is ON the screen should not blank out while Emerald Time is running (as if "Auto-Lock" was set to "Never"). Be careful with this when your device is not plugged in.

How to I turn on/off the ticking sounds?
Just go the the global Settings app on your home screen, scroll down to the item labeled "Time" (near the bottom) and slide the switch. The change will take effect as soon as you return to Emerald Time.

I can't get the brightness control to work.
You must first enable it in the Settings app. See above.

The screen has gone completely black!
You've probably turned the brightness down all the way. Just swipe up.

When I try to set the brightness I get the Notification Center instead (or vice versa).
The Notification Center only appears if the swipe is initiated at the very top of the screen. So avoid that area when setting the brightness; starting in the middle of the screen works just fine.
