[THREDDS #KKM-141749]: offsetsGreaterEqual



David,

Can bundle these files up and send them to us, or point us to where we can grab 
them?  We'd like to reproduce the behavior locally for testing and debugging.

Hello,

I am running the latest stable versions (as of May 20, 2013) of Java 
(1.7.0_21), Tomcat(7.0.40) and TDS(Version 4.3.16 - 20130319.1353).

I have 7 day hindcast/forecasts that run once daily with output every 2 hours 
that I am trying to put into an fmrc. My files are named using the the start 
date/time of the hindcast. I want to exclude the first 24 hours of each run 
from "Best" datasets. I thought using offsetsGreaterEqual="26" would do the 
trick but it only excludes the first 24 hours from run 0 and not from 
subsequent runs. Meaning, if I look at hour 26 of the "Best" dataset (the first 
record in that dataset) I'm getting data from the beginning (first 24 hours) of 
run 1 instead of hour 26 from run0.

Is this the intended behavior of offsetsGreaterEqual? If so I think the 
documentation at:

http://www.unidata.ucar.edu/projects/THREDDS/tech/tds4.3/reference/collections/FmrcCollection.html

should be clarified. Otherwise I'd like to report a bug.

Thanks,
David Robertson
