Detailed Description

Example: 

 #include "mbed.h"
 #include "PseudoRTC.h"

 PseudoRTC c;

 main()
 {
    time_t seconds;
    char buffer[32];
    c.set_time(1256729737);   // Set RTC time to Wed, 28 Oct 2009 11:35:37 (NOW WORKING ON mBuino)

    seconds=c.time(NULL);
    printf("Time as seconds since January 1, 1970 = %d\r\n", seconds);
    printf("Time as a basic string = %s\r", ctime(&seconds));   // ctime includes \n
    strftime(buffer, 32, "%I:%M %p", localtime(&seconds));
    printf("Time as a custom formatted string = %s\r\n", buffer);

     c.setTime(2014, 09, 20, 21, 05, 30);      // Second example: September 20, 2014, 21:05:30
     while(true) {
         printf("%04d/%02d/%02d %02d:%02d:%02d\r\m", c.getYear(), c.getMonth(), c.getDay(), c.getHour(), c.getMinute(), c.getSecond());
         wait(1);
     }
 }
