commit 61525ba967ac1bb7394ea0792aa6030bcbbad049
Author: Darren Tucker <dtucker at dtucker.net>
AuthorDate: Mon May 5 20:45:42 2025 +1000

    Handle systems that don't have st_mtim.
    
    Ignores nanoseconds, but it's checking for >1h old so a few nanoseconds
    shouldn't matter much.  Fixes build on Mac OS X.
