time dimension problem

[Zhangfan Xing <xing@xxxxxxxxxxxxxxxxxxxx>]

Hi, Jon and friends,

I am having problem to get LAS work properly with
a netcdf file that represents yearly averages. LAS says:

You specified a time or depth value that is outside the region contained
by this dataset.

I searched mail archive, found an old thread and followed suggestions
there, but still got same error. The URL of this old thread is
http://ferret.wrc.noaa.gov/Ferret/LAS/Mail_Archives/fu_2000/msg00032.html

Attched are relevant parts of my xml file and dump of my netcdf for time.

Thanks in advance.
