That's not surprising, because "Unix systems in general" do not have birth-time timestamps; they're a moderately recent innovation. Based on what little information I have at ready hand, they appeared in NetBSD sometime between 2000 and 2006 - a 2000-02-03 sys/stat.h doesn't have them while a 2006-02-24 one does - and FFS doesn't have them in FFSv1, only FFSv2. /~\ The ASCII Mouse \ / Ribbon Campaign X Against HTML mo...@rodents-montreal.org / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B
