Description Marko Hrastovec 2001-01-30 08:51:41 UTC

Kernel keeps the number of seconds about uptime. The numbers
can be found in /proc/uptime.

In kernel source uptime variable is declared as long.
(include/linux/kernel.h)

After cca. 500 days the counter resets because of overflow.
Uptime in seconds needs larger number type.

Comment 1 Michael K. Johnson 2001-01-30 21:30:16 UTC

This is by design; uptime has to be atomically updated.  Changing this
gets proposed over and over on linux-kernel, and is repeatedly rejected
for the same reason.
