Try the attached. There is one caveat: it won’t work correctly if you have a IPv6 Destination Options Header with the PDM option but also other option types in that same header.
Also, I have no idea if I did the time scaling correctly. BTW, there’s a bug in the draft: page 8 says for the Options Length field "This field MUST be set to 16.” But really the field must be set to 12, since that’s the length of the PDM option. -hadriel
