 When working with times and dates, it's useful to have the timezone used
 in WordPress, however there's no unified way to get it.

 `get_option('gmt_offset')` is filtered and the '''current''' offset is
 translated from the timezone string, but there's no reverse which is
 needed when working with relative times and dates.

 There are two ways we could handle this:
 1. Filter `timezone_string` and work out the correct string - This will
 likely break the admin interface for it.
 2. Introduce a new function to get the timezone from `timezone_string`,
 and fall back to `gmt_offset` if needed.

 Patch has implementation of the second option (also using DateTimeZone),
 can be adapted as necessary for the first.
