 Currently, the function `current_time()` expects
 `date_default_timezone_set()` is never used.

 Inspecting the code of `current_time()` confirmed this, because it formats
 the result using `date()` function (that is affected by timezone).

 In fact seems Wordpress always resets the timezone to UTC; an `echo
 date_default_timezone_get();` placed at top and at bottom of wp-config.php
 in a clean WordPress setup will prove this.

 So using `date_default_timezone_set()` anywhere in theme or plugin code
 will broke `current_time()`.
