Subject: [xen] add warning to 'time went backwards' message
Message-id: 20080312141046.22327.28505.sendpatchset@prarit.boston.redhat.com
O-Subject: [RHEL 5 PATCH]: Add Warning to Xen "time went backwards" message
Bugzilla: 436775

Add "Warning" to the "Time went backwards" message.

Most QA groups (if not all) grep for specific messages in the syslog such as
"Error", "Warning", "Oops".

Time went backwards is a key error which can result in system instability.
