-/** Implementation of the C time.h functions

- * Provides mechanisms to set and read the current time, based
- * on the microcontroller Real-Time Clock (RTC), plus some
- * standard C manipulation and formating functions.
- *
- * Example:
- * @code
- * #include "mbed.h"
- *
- * int main() {
- * set_time(1256729737); // Set RTC time to Wed, 28 Oct 2009 11:35:37
- *
- * 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 %p\n", localtime(&seconds));
- * printf("Time as a custom formatted string = %s", buffer);
- *
- * wait(1);
- * }
- * }
- * @endcode
