The problem is that the clock is wrong on mcidas.uww.edu (1 hour ahead)
so your LDM is always asking for future data (which the upstream feeder
doesn't have).  Here is the output from the date commmand:

[ldm@mcidas]$ date
Tue Nov 16 10:49:10 CST 1999
[ldm@mcidas]$ date -u
Tue Nov 16 16:49:18 UTC 1999
[ldm@mcidas]$ 

Right now, it is 15:47 UTC on my system.  You should reset the clock
and then restart the LDM.  It is probably a good idea to reboot
after setting the clock back.  You should also set up the time
service (xntpd) on your system so this problem will not bite you
in the future and your system clock will always be kept "on time".

He can sign up to any of the Unidata mailing lists at:

http://www.unidata.ucar.edu/mailing-list-form.html

I suggest at a minimum, he sign up for ldm-users and mcidas-x.

Thanks...same old problem.  I don't know why this keeps happening with that
particular machine.   We will get it set up with the time service.
