Hi Rick,
In one of the files that you sent, I see that the DATE-OBS fits header, which is the default used by AIJ, contains '2000-01-01T11:58:55.816', so indeed the timing will show up in AIJ correspondingly. If that date is indeed wrong, you'd have to edit the fits header value to correct the timing so that AIJ will report correctly. You could do that by hand using the AIJ fits header editor, but if you need to analyze a bunch of images, a python script to modify the time would save a lot of hand-editing time. Another approach would be to run your analysis, ignoring the timing. Then save the measurements table and open it in a spreadsheet program to edit the time. Then save as a tab-delimited file and reopen in AIJ for further analysis.
