Time zone auto isn't working

Location Services (including automatic time zone selection, Maps, and "Find My Mac") relies on a database of Wi-Fi access points with known locations. You don't have to be connected to a wireless network, but Wi-Fi must be turned on and within range of one of those access points. Otherwise the machine won't be located at all, or the location will be wrong. Sometimes the location will be wrong because the database contains inaccurate data. That would happen, for example, if you moved from one place to another and took your Wi-Fi router with you. The router is still listed in the database, but the location is wrong.

According to reports, if you connect to a Wi-Fi network with an iPhone, the location of the network will be sent to Apple and added to the database after a delay. An iPhone, unlike other Apple devices, has built-in GPS satellite navigation, and so can locate itself independently of Wi-Fi. The phone would have to be set to share diagnostic and usage information with Apple.

This procedure is a diagnostic test. It makes no changes to your data.

Please triple-click anywhere in the line below on this page to select it:

ls -@Oaen /e*/local* | pbcopy

Copy the selected text to the Clipboard by pressing the key combination command-C.

Launch the built-in Terminal application in any of the following ways:

☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)

☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.

☞ Open LaunchPad and start typing the name.

Paste into the Terminal window by pressing the key combination command-V. I've tested these instructions only with the Safari web browser. If you use another browser, you may have to press the return key after pasting.

Wait for a new line ending in a dollar sign ($) to appear below what you entered.

The output of the command will be automatically copied to the Clipboard. If the command produced no output, the Clipboard will be empty. Paste into a reply to this message.

The Terminal window doesn't show the output. Please don't copy anything from there.

Does the preference pane actually show that you're in New York but the time zone is Mountain? Or is it just that the clock doesn't adjust?

Incorrect date or time displayed in various applications

I can't restore defaults.

That's because the settings are already default.

Please read this whole message before doing anything.

This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.

Step 1

The purpose of this step is to determine whether the problem is localized to your user account.

Enable guest logins* and log in as Guest. Don't use the Safari-only “Guest User” login created by “Find My Mac.”

While logged in as Guest, you won’t have access to any of your documents or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this behavior; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.

Test while logged in as Guest. Same problem?

After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.

*Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.

Step 2

The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.

Please take this step regardless of the results of Step 1.

Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem.

Note: If FileVault is enabled in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Ask for further instructions.

Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.

The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.

Test while in safe mode. Same problem?

After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of Steps 1 and 2.

Step 1?

You didn't need to change any settings. The question was whether the clock was still wrong while you were logged in as Guest.

The location and the time zone are both correct. That's not the problem. The problem is that the clock is not showing the right time. I still don't know whether it was the same in the guest account.
