[ale] set time manually on a RHEL 5.1 server

[Jerry Yu]

'date' on that remote server returns "Thu Jan 17 22:04:24 GMT+1 2008".  I
verified the country is indeed "GMT+1".
The time above is correct now per the user local to the server.
However, this is only after I padded 2hours into the 'date -u' returned on a
server next to me, with TZ set to EST.
