Actually, it can depend on the platform, but for most of the recent ports,
you're absolutely right.  What you describe is exactly the intent.  The
clock will likely be numerically right after all that time, but you'll have
missed (delayed) any alarms and events that were set to occur in the
interval, and any other DSRs of course.
