[Bioperl-l] Wanting to inject date into a SeqIO object

[Hilmar Lapp]

Hi Dave,

$seq->add_date() is the right call, but not all output formats support  
dates. I don't remember exactly about the gcg format, but I do know  
that UniProt can have multiple dates, if that's what you want.

To clarify, did you actually try your second version below and found  
it not to work in the sense that the date did not show up in the  
output file?
