David,

It's likely that one or more of the time servers the "ldmadmin check" command 
is using is incorrect. The servers are set in the registry parameter 
"/check-time/ntpdate/servers". You should have some good time servers at GSFC. 
Try using them instead.

Alternatively, you can disable time-checking by setting the registry parameter 
"/check-time/enabled" to 0. I don't recommend this, however.
