Hi *,
while progressing on timecounters I tripped over
sys/time.h:
struct timeval {
long tv_sec; /* seconds */
long tv_usec; /* and microseconds */
};
A quick scan in the net gave that other systems
use time_t for tv_sec an suseconds_t for tv_usec.
I think this should be cleaned up when moving to
timecounters.
Currently amd64 defines time_t as int so there
seems to be some room for mismatches as usually one
expects tv_sec being assignable to a time_t type without
loss of precision.
So, the questions are:
- How can this be unified without
causing binary compatibility headaches?
- When do we officially switch to time_t being
a 64 bit quantity (2038 being not so far away :-))?
