(Sorry for the late reply - this wasn't in my Watched Topics)
Dates that are formatted with the 12-hour time don't show the AM (or PM) properly when using "Copy to Excel"/"Copy all as xls" - it appears like A1P1, or A4P4, or A10P10, or ... .
The fix that was made for the "Copy to Excel"/"Copy as xls" needs to be applied to the "Copy to Excel"/"Copy all as xls".
I haven't tried Version 10 yet to see if this is fixed there, but it occurs in 9.0.6.1665.
