Actually, it could be the problem is that I am running this on PowerPC.  
Specifically, I am thinking the calls to 
unpack "ddouble" which are marked as "machine dependent".  Running on Intel 
(10.5.7) does not have this 
problem, and it appears that dates are coming across wonky on PowerPC but look 
fine in Intel.  sigh.

OK, it appears the problem was endianess after all, and not some difference in 
the file format.  Converting the 
packed doubles to little endian seems to fix the problem.  Ignore the previous 
patch, attached is a new patch 
which checks endianess and converts to little endian if necessary.  I have 
tested it on both Intel and PowerPC 
macs.
