#include "mbed.h"
DigitalOut myled(LED1);
int main() {
printf("RTC example\n");
set_time(1387188323); // Set RTC time to 16 December 2013 10:05:23 UTC
printf("Date and time are set.\n");
while(1) {
time_t seconds = time(NULL);
//printf("Time as seconds since January 1, 1970 = %d\n", seconds);
printf("Time as a basic string = %s", ctime(&seconds));
//char buffer[32];
//strftime(buffer, 32, "%I:%M:%S %p\n", localtime(&seconds));
//printf("Time as a custom formatted string = %s", buffer);
myled = !myled;
wait(1);
}
}
为什么 1387188323 = 2013 10:05:23
