Expiration RulesExpiration is an important means to achieve key control with CyberKeys and CyberLocks. Regularexpiration and renewal reduces the exposure and subsequent risk of a lost or stolen key becausean expired key will not open locks. This form enables setting expiration "rules" to enable ongoingcontrol. In addition, a start date for the key may be set to prevent the key from working before itshould.Start Date - The "Start Date" is the day a key will begin working. By default, it is the day the key isadded to the system.Expiration Rules - CyberKey expiration takes effect as soon as it ceases to be the day or date ofexpiration. For most expiration rules, that means the key will work till the end of the day or datespecified. The key will expire as soon as the clock rolls to 12:00am, since the date will haveadvanced. Expirations rules of "minutes" or "hours" will set the key to stop working at a specifichour and minute of the day.Fixed Date - This rule simply sets a date after which the key will not work.Extend Expiration - Another option is to have the expiration move further ahead every timethe key is updated. This rule is often called a rolling expiration. Since there is no set day or datefor key expiration, the key's next expiration is calculated when the key is updated at acommunicator. Each time the key is docked at an Authorizer or IR Encoder, the time untilexpiration is reset to the interval specified in the input fields. Note that rolling expiration by days, weeks, or months extends the key's expiration to midnight (relative to the time zone of theAuthorizer contacted) of the last day.Example: A key with a one day extend expiration updated today at a communicator will be setto expire at the end of the day tomorrow.Note: A rolling expiration of minutes or hours takes priority over the time frames assigned to
