[ome-users] metadata vs OME-XML reporting of date/time

The value of the "AcquisitionDate" field in the OME-XML window is
already accessible via an ImageJ macro.  For example, if 'filename' is
the name of the file being opened:

// ---
run("Bio-Formats Macro Extensions");
Ext.setId(filename);
creationDate = "";
Ext.getImageCreationDate(creationDate);
print("Value of 'AcquisitionDate' is: " + creationDate);
// ---

This is part of the Bio-Formats macro extensions, documentation for
which can be viewed by clicking "Plugins > LOCI > Bio-Formats Macro
Extensions" in ImageJ.  There are also some example macros here:
