Yes, and it is trivial to write a fake date next to my signature. That
doesn't mean there are no legal implications. In fact, just as I can
commit fraud (under the right circumstances) by writing that fake date
on a piece of paper, I can commit fraud by using a fake time-stamp in
an OpenPGP signature.

Let's summarize: The signature time has potential legal implications.
