Hi Javier,

assuming that you refer to the ROI Manager's Multi Measure:
If you do NOT enable 'One row per slice', you can enable 'Display Label'
in Analyze>Set Measurements.
Then you will get a label in the form:
   ImageName:RoiName:SliceLabel
In your case, the SliceLabel would be the time.

If you DO use the 'One row per slice' output, I fear that you can't have
it with the current version of ImageJ:
RoiManager.multiMeasure(ImagePlus, Roi[], boolean) writes only the image
title, not the slice label.

What you could do is adding a column by a macro after running 'Multi
Measure'. It will be the last, not the first column, however.

   if (nResults() != nSlices())
     exit("Error: not one Results row per stack slice");
   timestamp = 0;
   for (i=0; i<nSlices; i++) {
     setResult("SliceTime", i, timestamp);
     timestamp=timestamp+0.1667;
   }

Note that Results Table rows are numbered from 0 to nResults-1 (in
contrast to stack slices, which are numbered 1 to nSlices).

Michael
