Is that due to dates past 2038, or something else?
Also dates before 1901 for 32-bit signed time_t, or before 1970 for unsigned time_t. I want the pre-1901 transitions to be checked, though, so I would rather stick with 64-bit signed time_t when generating the reference file. Plus, on some platforms zdump uses CRLF instead of LF to terminate output lines. There may be other niggling things like that.
I'd be testing something where time_t doesn't get involved at all, of course - an entirely different, non-C-based representation. That's the point of it, from my perspective.
Something with bignums, say? (Because 64-bit signed time_t doesn't suffice for simulations of proton decay in degenerate stars. See: Adams FC. The future history of the universe. Cosmic Update. 2011-07-23. http://dx.doi.org/10.1007/978-1-4419-8294-0_3 :-)
