Comment (by cnorris23):

 I'm with DJPaul on this. I've tried multiple combinations of timezone
 settings. The most convoluted was where PHP was set to one TZ, the server
 to another, and WP to another. I couldn't break anything. I then read the
 PHP documentation on the issue. As far as PHP is concerned, this is how
 the tz is determined (http://www.php.net/manual/en/function.date-default-
 timezone-get.php):

 1. The date_default_timezone_set() setting
 2. the TZ environment variable (PHP prior to 5.3.0)
 3. the date.timezone ini option
 4. the host OS
 5. if all the above fail, default to UTC

 WP uses date_default_timezone_set( 'UTC' ) very early on (in wp-
 settings.php) which means that to PHP, we're always on UTC. No matter your
 WP or server setup, all time is UTC, get_gmt_from_date() being the only
 exception. I think it's safe to mark this as invalid, but just in case:

 @sboisvert, can you provide some more details? Are you having this issue
 on all new posts, or is the time only off on old posts? With what specific
 components are you having this issue? What's your PHP version, and are you
 on a Windows or Linux server?
