Is there a New Virus out that changes your date?

Just wanted to ask some people around here if they've seen a virus that changes your system date to like June or July. All of a sudden 4 workstations at my work had their dates changed, and they were all the same. The "say" they didn't install any software or download anything, but I thought it was pretty weird.

Thanks

Are you sure these workstations didn't have their time synchronized with a network-server? Maybe your server's time was reset...

Frank! Where ya been?

Wow, Deja Vu.

And.... Good to see you again, Frank. Don't be a stranger.
