What is the output of "src/uptime --help"?  It should say something like this:

If FILE is not specified, use /var/adm/utmpx.  /var/adm/wtmpx as FILE is common.

except the file names will differ, e.g., the first file might be
"/etc/utmp" on your host.  Can you see what is in the file
"/etc/utmp", or whatever its name is?  There should be a boot time in
there, in some binary format.  If not, that would explain the problem.

For example, on a Solaris 8 host, the command "od -cx /var/adm/utmpx"
outputs this:

0000000  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0
        0000 0000 0000 0000 0000 0000 0000 0000

        0000 0000 0000 0000 0000 0000 0000 0000
...

and since /usr/include/utmp.h contains this line:

#define     BOOT_MSG        "system boot"

uptime knows that the system boot time was 0x40bc7522, which was
2004-06-01 12:22:58 UTC.  HP-UX should have something similar.  At
least, that is what its documentation says.

Possibly your /etc/utmp file is corrupted?
