Here is a table of the FITS timing test results posted and e-mailed to
me so far. There is definitely alot of work that needs to be done
here.  If your package is not in this list then please take the test
and post the results. After we stop receiving results then we'll post
recommendations for how to take this behavior into consideration for
the various packages:

Regarding MaximDL:

Brad Walter posted:
"I observed and reported to the CCD discussion group on 12/29/2004 that,
when combining a series of images in Maxim/DL, the program sets a time
for the combined image equal to the time of the series member selected
as the reference for the combination, rather than the earliest member.
It also sets the exposure duration as the sum of the exposure durations
of the images being combined. Then the photometry tool in Maxim/DL sets
the observation time for the corresponding photometry data table record
as the arbitrarily selected image time plus half the summed exposure
time saved in the header for that combined image file."

Keith Graham added:
"1. Note the times of the first and last images in my series.
2  Add the exposure duration to the exposure time in the last image.
3. Determine the time midway between the starting time of the first image
and the ending time of the last image as the time for the stacked exposure."
