Steven Hawkins commented on TEIID-616:
--------------------------------------

We talked about this at the time the change was made.  The notion of a system start time in a cluster is very hard to define.  Previously we implicitly/explicitly managed the notion of startup time primarily around the idea of the current configuration vs. next startup.  Now that we only have a single configuration every process restart represents a possible "next startup".  Thus the eldest process is the system start time based upon configuration.  What would you propose start time to be defined as?

> The system start time is determined by the Eldest Process start time.   This is not a 100% guaranteed to be true in all cases.   In a rare cases where proceses are brought down and backup, the oldest process start time might not represent how long the system had actually been running.
