Question: How can I force the target's DTS to be the source's DTS?
Add "-copyts" to the front of the command-line as a global option.
The ffmpeg application will automatically rebase timestamps to zero
after demuxing unless you specify this option (which is further up the
pipeline than your bsf, hence the bsf has no effect).

Thanks, Devin, but nope, they're a lot closer but they're still not the same.
