So, I still haven't got a satisfactory answer to at least part 1 here. The only thing I can find close to it on CPAN is Time::Local, which specifically says that denormalised values give unspecified behaviour. That will be no good to me. I'm also thinking I should rename the module to Time::timegm, providing a single timegm() function, partly because some OSes (notably GNU libc and BSD) already provide a timegm(3) function, so a later version of this module could just provide XS wrapping of that if required.
