Greetings Akshay,
I think the issue is that you are extracting the date from the filename
(good), but are rewriting the information using the NCML ouside of the
aggregation (i.e. <values start="0" increment="1" />). Can you try using
the same NcML you have, but remove this part of the NcML:
<variable name="TIME" type="double" shape="TIME">
<attribute name="units" value="months since 1960-01-01 00:00:00" />
<values start="0" increment="1" />
<attribute name="axis" value="T" />
</variable>
Thanks!
