Here's what I think is a better version, especially as I suspect that time()
could possibly delay.
static time_t baseSeconds = 0;
static uint64_t baseMilliseconds;
if (!baseSeconds) {
baseSeconds = time(NULL);
baseMilliseconds = grub_get_time_ms();
}
{
uint64_t milliseconds = grub_get_time_ms() - baseMilliseconds;
now->seconds = baseSeconds + (milliseconds / MSECS_PER_SEC);
now->nanoseconds = (milliseconds % MSECS_PER_SEC) * NSECS_PER_MSEC;
}
