Patrick,
the timeUnitsChange only affects to the aggregation coordinate variable,
that means, only the variable with same name that the aggregating
dimension will be affected.
how to solve you problem? hmmmmm
* Modify the java source code for the Aggregation which modify all the
variables with the a _CoordinateAxisType="Time". At least that the
timeUnitsChange look at the _CoordinateAliasForDimension in case
your "coordinate" variable has a different name from aggregation dim:
http://www.unidata.ucar.edu/software/netcdf-java/reference/CoordinateAttributes.html
* An interim solution could be, create a new variable for the
time_bnds, ans use the value element to indicate the start value and
increment.... this needs a better thinking
probably I'm wrong and now I'm missing something.
Regards
Antonio

Patrick,
from the aggregation documentation :
http://www.unidata.ucar.edu/software/netcdf/ncml/v2.2/Aggregation.html
when the units of the aggregation coordinate change on the existing
coordinate variables, you must add timeUnitsChange="true" on the
aggregation element:
Ok I have rebuilt an aggregation using this element.
Now the time axis is correct but I note that the time_bnds is not
treated and has kept the different
time references
As consequence, I get with ferret
yes? use
"http://vesg3.ipsl.fr/thredds/dodsC/cmip5.merge.CNRM-CERFACS.CNRM-CM5.historical.mon.ocean.Omon.r1i1p1.tos.1.aggregation";
*** NOTE: Error in bounds "time_bnds" or bounds do not enclose point
on axis time
*** NOTE: Substituting coordinate midpoints
Have I missed something again ?
Thanks
Patrick
