With the Debian Lenny kernel, I get: Uptime: 198.840 days (since Sat Feb 02 00:01:06 2008) Uptime: 199.637 days (since Fri Feb 01 04:55:34 2008) Uptime: 199.637 days (since Fri Feb 01 04:57:27 2008) Uptime: 198.838 days (since Sat Feb 02 00:10:15 2008)
Interesting numbers. The max difference in these numbers is very nearly 2^16 seconds. 199 days is very nearly 2^24 seconds. Perhaps there is an endianness problem in the timestamps some kernels use?
