-Cron expression of the portfolio vulnerability analysis task.  
+Defines how old a project's analysis may be, in milliseconds, before it is analyzed again.  <br/><br/>  Note that analyses triggered by BOM upload or manually via API also cause a project's  last analysis age to be reset. Projects that are analyzed frequently are thus rarely  or never analyzed on schedule. This avoids redundant work.
