Well, Harald you're right.

From POSIX one could use select(2) timeout parameter as model where 
'struct timeval' is being used

    http://www.opengroup.org/onlinepubs/009695399/functions/select.html

with 'time_t' used as struct members. Use of 'struct timeval' as
datatype for hardWallclockTimeLimit I'd dare to rule out, as there
is probably no scheduler considering wall-clock time limits with
nano-second precision.
