# time.timezoneOffset

The timezone offset in minutes. Positive values are west, negative values are east of UTC, as in the ECMAScript getTimezoneOffset method. Use this to display UTC based data in a predefined time zone.

This option is deprecated as of v11.4.1 and will be removed in a future release. Use the time.timezone option instead.
