According to the marketing plan, some promotions might be available for
a specific period of a day and days in a week. The schedule page allows
to answer this type of promotion structure, by enabling the mark related
to the period you need.
In this example, the 2.00 $ discount is available only from 11:00:00
to 14:59:59 and from 18:00:00 to 19:59:59. If the time is outside these
ranges, the discount will not apply.
