Hi all!

This is my first post to this mailinglist, so be gentle :-)

I hope you can help me with this very strange issue I'm having...
I have an application in JRuby on GlassFish deployed on 2 servers. One
is production, the other is fail-over. We had an power outage a few
days ago, and now I'm having a strange issue on the production server.
It seems that the application (NOT the server) is slowly losing track
of time...

I've investigated the log file, and here are some results, consider
the times:

[#|2009-06-04T15:00:00.446+0200|INFO|sun-appserver9.1|

This gets worse:

As you can see, the time goes way off!!!

How can this be happening? Is there a way I can sync time in JRuby
(GalssFish doen't seem to be the issue) with the server time?

Anyone with some help/anwsers/hints?

With kind regards,

David Westerink
