+   * Attempts to set the PHP maximum execution time.
+   *
+   * This function is a wrapper around the PHP function set_time_limit(). When
+   * called, set_time_limit() restarts the timeout counter from zero. In other
+   * words, if the timeout is the default 30 seconds, and 25 seconds into script
+   * execution a call such as set_time_limit(20) is made, the script will run
+   * for a total of 45 seconds before timing out.
+   *
+   * If the current time limit is not unlimited it is possible to decrease the
+   * total time limit if the sum of the new time limit and the current time
+   * spent running the script is inferior to the original time limit. It is
+   * inherent to the way set_time_limit() works, it should rather be called with
+   * an appropriate value every time you need to allocate a certain amount of
+   * time to execute a task than only once at the beginning of the script.
+   *
+   * Before calling set_time_limit(), we check if this function is available
+   * because it could be disabled by the server administrator.
+   *
+   * @param int $time_limit
+   *   An integer time limit in seconds, or 0 for unlimited execution time.
+   *
+   * @return bool
+   *   Whether set_time_limit() was successful or not.
