In order to use this widget you will need to know 3 things, the web server name where the Kronos application is running, a valid user name and valid password.
For the server name, it should just be one word (e.g. time or kronos) or name.companyname.com (e.g. time.company.com), depending on how IT has it set up. Your IT dept should be able to give you the name if you have any questions. If you have a link to the Kronos application that is something like kronos/wfc/logon please remove the /wfc/logon from the server name.
