Everytime one updates the kernel time and it gets set *back*, make will notice the derived objects (ie libdb.a) are newer than current time and complain. However, I suspect the kernel isn't keeping time perfectly and updating from the HW clock (YMMV: historically, some servers had better RTC crystals) is causing the problem. Having a bad RTC will also look like the kernel isn't keeping time when in fact it is. a500# date Thu Apr 19 11:11:02 MDT 2001 a500# hwclock Thu Apr 19 11:11:01 2001 -1.003308 seconds a500# uptime 11:11:36 up 21:25, 1 user, load average: 0.00, 0.04, 0.04 So not doing too badly - but it needs to be fixed. I'm assuming the A500 has a good RTC. I'll submit a bug for you. grant Grant Grundler parisc-linux {PCI|IOMMU|SMP} hacker +1.408.447.7253
