End User: We have testing today and the machines need their clocks set back to 4/16.
Me: Huh? You cant do that because of the master time server.
End User: Well thats what the email says is supposed to happen.
Me: Email?
End User: Email.
Me: Nobody sent us any email.
End User: I can forward it to you.
Me: Sure, what time is your testing supposed to start?
End User: 9:30
Me: Its 10:02 now.
End User: Yeah.

So needless to say I checked the email, Nobody in my dept was copied in. I figured out a way to get around the master time server and another helpdesk person made the changes and logged in the testers.

You would think a big corporation would be alittle more co-ordinated. But the day was saved at the last minute.
