What changes and/or events cause the Last Modified Date/Time to be updated?
There are a few ways for an ACID to have the Last Modified Date updated:
1.) TSS LIST(acid)' can cause the Last Modified Date to be updated.
2.) If the ACID in question owns a Resource, which is Permitted to another ACID, the Last Modified Date will be updated to allow CA-Top Secret to keep track of the WHOHAS pointers.
3.) TSO Signon or Signoff will cause an update to Last Modified Date.
