Hi Josh, 

The current LDM/IDD topology delivers real time data.

Note: You can, if noticed early, change your request with a -o flag
to change from the default one hour (3600 seconds, the -o enjoys seconds) to a 
larger value.

IF the upstream you are requesting from has a large queue (larger than 1 hour) 
this can be used
to grab older stuff that still persists in the upstream queue.

Most data and products in the LDM/IDD, that have aged off the queue, can be 
pulled from:

or

Hope this helps,
