Dear Costas -- I am not aware of anything to do that, but a while back
I wrote a patch that allows an additional format specifier, %s{....}
which runs a script and argument that are specified in the {....},
and the result of that script is used as the file name for the log
file.  It would be easy enough, given that functionality, to write
a script that returns a time stamp.  I will see if I can narrow this
down to a small patch that I can submit, and when I do, I can email
you the patch at the same time.  I did this a while ago, but if this
part of the code has not been changed a lot, then the patch should
not be too bad to extract.

I've been meaning to submit it for some time, actually, and this is
a good prompt to make me do it!
