I don't think there is a need to include such data in commit message. A 
commit message should say what is done and why it's done (and sometimes 
how it's done, in case of some complex code being added) and I guess 
that's all.

Please use clock macros instead of numbers, as introduced by Andrzej 
Hajda's patches merged to Kgene's tree.

Best regards,
