OS X conforms to the SUSv3 specification, which says explicitly in the documentation for <sys/stat.h>: "Times shall be given in seconds since the Epoch." The docs don't really *have to* say, though, because it's the only choice that makes any sense. The behaviour on Windows is obviously wrong---imagine what might happen if you read a time from the filesystem, then the user changes the time zone, *then* you convert it from local time to UTC, but using the *wrong* local time! You can't even remember which time zone you were in before reading the time, because the user could change it between you remembering it and you reading the time.
