An upstream LDM on Striker2 was feeding NLDN data to Anvil.

An upstream LDM-5 process on Striker2 was started in response to a
NOTIFYME request from Anvil.  The start-time for the data is 2004-05-12
20:28:23.588 UTC, which is about FIVE HOURS IN THE FUTURE!

Is there something wrong with the clock on Anvil?

NOTE: The notifyme(1) program uses LDM-5 protocols rather than LDM-6
protocols.

The upstream LDM-5 on Striker2 was unable to to send a do-nothing
NULLPROC message to its downstream LDM-5 counterpart on Anvil.

An upstream LDM-6 process on Striker2 was started in response to a
FEEDME request on Anvil.  The start-time for the data is 2004-05-12
19:37:13.933 UTC, which is about FOUR HOURS IN THE FUTURE!

The upstream LDM-6 process on Striker2 was unable to send a do-nothing
NULLPROC message to its downstream LDM-6 counterpart on Anvil.  The
connection was closed and the upstream LDM-6 process on Striker2
terminated.

Questions:

    1.  Are the times in Striker's logfile correct?  They should be
        UTC.

    2.  Is there something wrong with the clock on Anvil?
