Previously, if the system time was adjusted backwards during a progress display, get_update_timediff return negative values prevent the progress bar from updating.

Have you considered using clock_gettime(CLOCK_MONOTONIC) rather than gettimeofday()? Or is it not available on some platforms? Even if you have to use a different function for OS X or something it mightn’t be much worse than these backwards time hacks.
Dave also pointed this out to me on IRC. Unfortunately, it looks like it is indeed not available on OS X. If there is a suitable replacement function on OS X we could go the platform-specific route, otherwise it hardly seems worth it as we'd just end up having to do all of the same hacks in the OS X branch. It looks like OS X has clock_get_time, but I'm having trouble finding proper documentation for it to determine if it's suitable.
