ud does check /proc/uptime. How did you arrive at the 49.7 number? It
is definitely not the case on this 2.6.8 machine:
$ cat /proc/uptime
20859988.28 2609303.78
$ expr 20859988 / 24 / 60 / 60
241
As far as I can tell, the number of seconds since boot time is stored in
a 32-bit integer, which should be enough for 68 years.
I don't think the problem here is determining the uptime; it's in making
sure a single boot time doesn't have duplicate records.
Thanks,
Matej
