Ah, seems like it's really Winsock's fault: https://docs.microsoft.com/en-us/windows/win32/api/winsock/ns-winsock-timeval which compares unfavorably to the POSIX wording The <sys/time.h> header shall define the timeval structure, which shall include at least the following members: time_t tv_sec Seconds. suseconds_t tv_usec Microseconds. regards, tom lane
