You mean you want to do it outside of SNMP?  You can always go look
through the code to find it.  See the get_uptime() code in snmplib/system.c

Linux. Any API?

SNMPv2-MIB::sysUpTime is indeed the uptime of the agent:

  DESCRIPTION   "The time (in hundredths of a second) since the
            network management portion of the system was last
            re-initialized."

If you want the system uptime, then you want this one instead:

HOST-RESOURCES-MIB::hrSystemUptime
hrSystemUptime OBJECT-TYPE
  -- FROM       HOST-RESOURCES-MIB
  SYNTAX        TimeTicks
  MAX-ACCESS    read-only
  STATUS        current
  DESCRIPTION   "The amount of time since this host was last
        initialized.  Note that this is different from
        sysUpTime in the SNMPv2-MIB [RFC1907] because
        sysUpTime is the uptime of the network management
        portion of the system."
