However, it looks as though I was wrong:
linux/time.h:
struct timeval {
time_t tv_sec; /* seconds */
suseconds_t tv_usec; /* microseconds */
};
time.h:
typedef __time_t time_t;
sys/time.h:
typedef __suseconds_t suseconds_t;
bits/types.h:
__STD_TYPE __TIME_T_TYPE __time_t; /* Seconds since the Epoch. */
...
__STD_TYPE __SUSECONDS_T_TYPE __suseconds_t; /* Signed count of microseconds
*/
bits/typesizes.h:
#define __TIME_T_TYPE __SLONGWORD_TYPE
...
#define __SUSECONDS_T_TYPE __SLONGWORD_TYPE
bits/types.h:
#define __SLONGWORD_TYPE long int

Just because I've written it doesn't mean that
either you or I have to believe it.
