Hi Dave, Robert,

Thanks for the help!

Dave: There are no options for time zones in the BIOS clock. The time
is just "there" to be set. It is currently set to 7:08 PM, which is
the current Central Time.

Robert: Great idea! I am fairly certain that is a good direction to go
in. I will check this on Tuesday (next time I am in the office).
