get_gmt_from_date() │ WP 1.2.0

Converts the specified date to the site's timezone, to GMT/UTC zone. Accepts date in the format Y-m-d H:i:s.

It is implied that a NON GMT date will be passed, but a local date.

The format of the returned date can be overridden in the second parameter. However, the passed date must always be in the format Y-m-d H:i:s.

Translates the date based on the option timezone_string (example value: Asia/Tashkent). If such an option is not available, then the setting gmt_offset is used (example value: 5, 6, -3, -4...).

To, on the contrary, get the local date from GMT, use get_date_from_gmt()

Uses: get_option()
