Problem with timezone

Hi, first of all, thank you very much for this very helpful plugin!
I do have a problem though.
As you may notice, we should setup the same time zone for local(computer) and server, otherwise, we will get some missed schedule posts.
When I setup the timezone of my Computer/Server/WordPress the same as my local time (which is UTC-8,Los Angeles, US), Auto Post Scheduler will display a kind of weird time(8 hour behind my timezone, = UTC-16, actually no such timezone) and won’t work on schedule time, of course.
Everything is fine when I setup all timezones (Computer/Server/WordPress) to UTC, but I prefer to use my local time instead of UTC time, if it’s possible.
Please advise. Thanks.

Hello,
APS uses the current local time of the server and the Timezone set in WordPress->Settings->General.

When you enable APS what does it display at the top? It should be something like

Current Status: Enabled

Current server time:2014-12-22 09:29:28 America/New_York
Next auto post check:2014-12-22 10:28:50 America/New_York

Hi, Thanks for your reply.
There are 3 places setup timezone: 1)server, 2)wp_settings.php, 3)WordPress->Settings->General.
When I change number 2 (via my theme function, of course. It’s not a good idea to touch the WP core, right?) to my timezone by
date_default_timezone_set( 'America/Los_Angeles' );
Auto Post Scheduler will display the weird time, 8 hour behind my timezone.
I tested this all the day to make sure. see table below(yes=correct, no=wrong):
```
Server:      LA    LA     UTC    UTC
WP_settings: LA    UTC    LA     UTC
WP option:   LA    LA     LA     LA
APS:         NO    YES    NO     YES
```

Why would you need to change wp_settings.php? Sounds like it is converting the timezone offset twice. Try it without.

APS gets the local time via the WordPress function
current_time(“timestamp”)

Yes it looks like double dipping when you call date_default_timezone_set() in your code.

Added this to functions.php to test
```
function heartbeat_debug() {
        error_log('Local Time: ' . date('Y-m-d H:i:s',current_time("timestamp")) . " " . get_option('timezone_string'));
        error_log('GMT Time: ' . date('Y-m-d H:i:s',current_time("timestamp", 1)) . " GMT" );

        date_default_timezone_set( 'America/New_York' );
        error_log('calling date_default_timezone_set');
        error_log('Local Time: ' . date('Y-m-d H:i:s',current_time("timestamp")) . " " . get_option('timezone_string'));
        error_log('GMT Time: ' . date('Y-m-d H:i:s',current_time("timestamp", 1)) . " GMT" );
}

add_action('wp_head', 'heartbeat_debug');
```
Outputs:
[23-Dec-2014 15:16:50 UTC] Local Time: 2014-12-23 10:16:50 America/New_York
[23-Dec-2014 15:16:50 UTC] GMT Time: 2014-12-23 15:16:50 GMT
[23-Dec-2014 10:16:50 America/New_York] calling date_default_timezone_set
[23-Dec-2014 10:16:50 America/New_York] Local Time: 2014-12-23 05:16:50 America/New_York
[23-Dec-2014 10:16:50 America/New_York] GMT Time: 2014-12-23 10:16:50 GMT

>Why would you need to change wp_settings.php?
Same timezone as my local computer.

>Sounds like it is converting the timezone offset twice.
Exactly.

That’s what WordPress->Settings->General->Timezone is for.
