The problem is that the time unit is not properly formatted.  You have:

minutes since    0-1-0 0:0:0

you need:

minutes since 0000-01-01 00:00:00

It's just a matter of  having a properly formatted unit.

You could cut and paste this NCML into a file (e.g. test.ncml)
in the same directory as your file and load that in to the IDV to 
get you started instead rewriting the file with correct units:

<?xml version="1.0" encoding="UTF-8"?>
<netcdf xmlns="http://www.unidata.ucar.edu/namespaces/netcdf/ncml-2.2";
      location="FOSTER.timegcm1.2.py2j001.nc">

    <variable name="time">
        <attribute name="units" value="minutes since 0000-01-01 00:00:00" />
     </variable>

</netcdf>
