The time stamp specifying when the client-principal object will expire. If the client-principal object expires before you can seal or validate it, and you attempt to use it, the AVM sets the LOGIN-STATE attribute to "EXPIRED" and you can no longer validate or use the client-principal object.
Note: If you set the attribute to the Unknown value (?), the client-principal is reset to have no expiration.
You can set this attribute to any DATETIME-TZ value, with the following limitations. The value of this attribute:
Is truncated to the second
Can have no greater precision than seconds
Can have a minimum value of 1/1/1970 00:00:01.000-00:00
On 32-bit platforms, can have the following maximum value: 1/19/2038 00:00:00.000-00:00
On 64-bit platforms, has no meaningful maximum value
Any attempt to set a value that does not conform to these limitations returns a message in the ERROR-STATUS system handle and leaves the previous value unchanged.
If not set or reset to the Unknown value (?), the AVM will never place the client-principal object in an EXPIRED login state. In either case, reading the attribute returns the Unknown value (?).
