What's going on is the time taken to run the task is added on to that period.
I suggest you use this instead:
http://wiki.jboss.org/wiki/Wiki.jsp?page=QuartzSchedulerIntegration
which is more reliable and has "cron"-like scheduling features and is more
robust.
Or, you could come up with a bug+patch that fixes the drift. It'd be an easy feature
to add.
