Use fixed-size fields in the structure for the timed protocol. This

Browse source 
includes changing a struct timeval to an explicit structure of two
int32_t's.  This requires using temporary timevals in several places
when calling gettimeofday(), settimeofday(), etc.  With this timed now
works properly on 64-bit platforms such as Alpha.
