I see this at work as well on our NetApp's (disk farms) and I only see 
messages about time skews but it doesn't hurt anything.. I'd suggest you 
talk to them about implementing a NPD daemon on all affected machines to 
sync the time up to a master time server.. It's very easy and fairly 
fool proof.. That's the best plan IMHO!
