Use casts or intermediate variables to remove a number

of platform/compiler-dependent warnings when handing
struct timeval fields, both reading and printing them.

It is a lost battle to handle the different ways struct timeval
is handled on the various platforms and compilers, so try
to be pragmatic and go through int/long which are universally
supported.
