Then it seems, when this is turned into an absolute time it is wrt UTC rather than the local time zone on the host computer. Am I wrong?

I don't know if this is relevant, but still:  My Shearwater Petrel, 
which has a very similar firmware, does not care about timezones at 
all.  I've got no problems with it whatsoever.

But I *did* have problems with an earlier Subsurface version back in May 
[1].  That was solved with an updated version of libdivecomputer.  What 
version do you have, James (run ./subsurface --version)?

Cheers,
Henrik
