Can't generate output for dataset with single-point time axis
Hi,
I am investigating how to get GrADS running behind LAS.
I loaded a dataset on my test system with only a single time to see what
kind of XML the LAS UI would generate. However there is a problem - the
time value being sent in the XML request is invalid.
This is the dataset:
http://monsoondata.org:9090/dods/gswp/grid/fixed/vegclass_bats.info
The addXml script generates the following:
<datasets>
<vegclass_bats
url="http://monsoondata.org:9090/dods/gswp/grid/fixed/vegclass_bats"
doc="" name="BATS cover classification interpolated to 1x1 degree">
<variables>
<vegclass name="landcover class ">
<link match="/lasdata/grids/vegclass_bats_time_lat_lon_grid"/>
</vegclass>
</variables>
</vegclass_bats>
</datasets>
<grids>
<vegclass_bats_time_lat_lon_grid>
<link match="/lasdata/axes/vegclass_bats_time"/>
<link match="/lasdata/axes/vegclass_bats_lat"/>
<link match="/lasdata/axes/vegclass_bats_lon"/>
</vegclass_bats_time_lat_lon_grid>
</grids>
<axes>
<vegclass_bats_time units="days" type="t">
<v>1982-Jul-01 00:00:00
</v>
</vegclass_bats_time>
<vegclass_bats_lat units="degrees_north" type="y">
<arange start="-59.5" step="1" size="150"/>
</vegclass_bats_lat>
<vegclass_bats_lon units="degrees_east" type="x">
<arange start="-179.5" step="1" size="360"/>
</vegclass_bats_lon>
</axes>
but when I generate a request, it comes out with the time set to Jan-16,
like this:
XML: <?xml version="1.0"?><lasRequest package="" href="file:las.xml"
><link match="/lasdata/operations/grads" /><properties ><ferret ><size
>.5</size><format >grads</format></ferret></properties><args ><link
match="/lasdata/datasets/vegclass_bats/variables/vegclass" /><region
><range low="18.0" type="x" high="70.0" /><range low="-1.0" type="y"
high="66.0" /><point v="16-Jan" type="t" /></region></args></lasRequest>
CACHE: true
And even when I try to do a ferret plot i get this message:
--
Illegal Limits
Sorry ...
There are no data available at 16-JAN 00:00
The data begin at 30-JUN-1982 12:00 and continue to 01-JUL-1982
12:00
Please try again with a time that lies within this range.

I am unable to find where this time value is getting set in the servlet
code. Please help..
Thanks,
- Joe
