[ome-users] Mac vs PC problem with ND2 files?

[Melissa Linkert]

Hi Michael,

As mentioned in the thread initiated by David Depoil:

http://lists.openmicroscopy.org.uk/pipermail/ome-users/2012-October/003352.html

...the problem is that the file modification date is used as the
acquisition date, which is not always entirely reliable.  Given that the
absolute acquisition time does not appear to be stored in the files,
we may not be able to do much about this.

Regards,
-Melissa

He has tried with both Fiji and ImageJ.  Would somebody else who has ImageJ on a Mac and has ND2 files please check this?
