What in the purpose of using a time condition?

 A time condition is a type of activation condition that can be applied to a guide to control when it is available to the user. A time condition can specify a start date and time, an end date and time, or both. This way, a guide can be restricted to a certain time frame, such as a specific day, week, month, or year. For example, a time condition can be used to show a guide only during a holiday season, a promotion period, or a system maintenance window. References: Oracle® Guided Learning User Guide, Guide Activation and Conditions editor, Oracle Guided Learning Content Developer Certified Foundations Associate
