>Description:
	Citing SUSv2:
    The <sys/time.h> header defines the timeval structure that includes at least
    the following members: 
    time_t         tv_sec      seconds
    suseconds_t    tv_usec     microseconds

NetBSD has a "long" as tv_sec. time_t is always a 32-bit integer.
This is a serious problem on LP64 platforms, consider eg code like
	tm = gmtime(&tv.tv_sec);
>How-To-Repeat:
	see above
>Fix:
	Change "struct timeval" accordingly. Unfortunately this leads to an
ABI change on LP64, so versioning of the affected library functions is needed.
