You can assign, in addition to individual time, an individual list of work days. For instance, you can create the list "First work day", so that an employee can have access to the equipment room in order to do the maintenance work on the first work day of the month. All lists are registered in a key management system message log. Entries are made in the message log whether or not servers are connected with a software. The software is only needed for creating a database and generating reports.
