HI Carlos,

First, you'll have to add "template" to the OPTIONS line in your control 
file:

OPTIONS YREV TEMPLATE

Next, your data set name looks strange to me; I believe your file names 
are of the form %y4%m2%d2 (you have an extra "m" between %y4 and %m2):

DSET ^uvief%y4%m2%d2.hdf

Finally the bigger issue...   There is no time dimension in the HDF 
files.  See how the XDEF and YDEF are referencing dimensions "fakeDim1" 
and "fakeDim2"; you'll need something similar for time.  You could use 
one of these same dimensions, and that should work, but I don't know 
what happens if you try and access data beyond the maximum.  For example,

TDEF fakeDim0 360 linear 01jan2003 1dy

should allow you to access 360 days of data.  I'm not sure what happens 
if you change the 360 to something larger than fakeDim0, e.g., 3650 to 
get 10 years, but you can try and then let us know.

Jim
