Hi Raul-

I apologize for the delay in responding.  I thought I had a quick
answer, but I had to relearn some Jython first.

If you try the following Jython procedure, it will return a
visad.DateTime object that contains the starting date/time of the
image:

def getImageTime(imagesequence, i):
   from visad.meteorology import *
   dateTime = None
   if isinstance(imagesequence, ImageSequence):
       sbi = imagesequence.getImage(int(i))
       dateTime = sbi.getStartTime()
   elif isinstance(imagesequence, SingleBandedImage):
       dateTime = sbi.getStartTime()
   return dateTime

If you want to use this interactively, you could create an IDV formula 
to call this which would look like:

getImageTime(imagesequence, user_Step)

This will prompt the user to enter the time step for the image they want.
