The Bellcore service is properly a timestamping service and not a
signature service. Their timestamp is constructed out of hash
functions, not digital signatures.
The algorithm is patented. Contact Bellcore for licensing. I'm not
sure they are going to license; they may decide that they want all the
timestamping revenue themselves.
