20010215: Starting the LDM



Erick,

I ran notifyme to ATM20 and still don't see any data files in your queue.
Everything appears correct- but can you check your system date/time
to make sure you have the correct time.

If your system clock is off, then all data that arrives at your end could
be ignored as too old.

Your mail header seems to show that the message you composed was at
6:11PM PST (this would roughly be be 0211Z) but your log messages are for
a time in the future, eg 0254Z. This could mean that your clock is 
about 1 hour in the future...making the LDM think that all the data it
is receiving is over 1 hour old.
