Just FYI, I actually had tried dnstap-ldns before.  The reason I had gone with dnstap-read was that I liked the fact that it broke down the packet components with finer granularity, e.g., the flags and options in the EDNS section.  I guess if I want the higher fidelity timestamp, I'll need to implement that breakdown myself.
