The office_hours directive

The office_hours directive expects a list of time ranges separated by spaces in the format: "HH:mm-HH:mm". The hours should be in 24 hour format, and the minutes are optional. The word "closed" can be used to indicate that the server is not operating on that day.

The first range will be used as the default value, and the rest will be read from right to left, starting with sunday.

When the current time is within those hours, the server will operate as usual, otherwise it will return a 403 with a page showing the operating hours of the service. See this example for a page that's always closed[2]

=> [2] A page that is never open.

Example 1: Open 24 hours

Don't use this directive.

Example 2: Open every day from 08:30 AM to 7:00 PM

The office_hours_additional_information directive
