You seem to be correct.  This is from rfc1213-mib.txt

          sysUpTime OBJECT-TYPE
              SYNTAX  TimeTicks
              ACCESS  read-only
              STATUS  mandatory
                      "The time (in hundredths of a second) since the
                      network management portion of the system was last
              ::= { system 3 }

Therefore the definition of system.sysUptime is, in fact the network
managaement susbsystem uptime, and not the host system total power on
uptime, and should not be represented as such.
