Hi,

Would it be possible to modify the GenBank writer to output the date in the
LOCUS header. When reading GenBank files this is already parsed in the correct
format into record.annotations, so the following patch would work:

 diff -u InsdcIO.py InsdcIO-date.py
--- InsdcIO.py  2009-11-30 19:54:05.000000000 +0000
+++ InsdcIO-date.py     2009-11-30 19:55:32.000000000 +0000

                         str(len(record)).rjust(11),
                         units,
                         mol_type.ljust(6),
-                        division)
+                        division,
+                        record.annotations.get('date', '01-JAN-1980'))
         assert len(line) == 79+1, repr(line) #plus one for new line

         assert line[12:28].rstrip() == locus, \


I realise you might not work when converting between different record types,
but this would suit my needs for the time being. 

Cheers
