Welcome to the Highcharts JS (highcharts) Options Reference

These pages outline the chart configuration options, and the methods and properties of Highcharts objects.

Feel free to search this API through the search bar or the navigation tree in the sidebar.


A callback to return the time zone offset for a given datetime. It takes the timestamp in terms of milliseconds since January 1 1970, and returns the timezone offset in minutes. This provides a hook for drawing time based charts in specific time zones using their local DST crossover dates, with the help of external libraries.

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