Remove offending use of datetime.now().

I don't really understand why this happens but I wonder if it might be
because we 'from datetime import datetime' twice through the wildcard
inclusion of certtools.

Should stop do wildcard include and instead do

from certtools import create_ssl_context, get_sth, get_proof_by_hash, verify_inclusion_proof, write_file
