How about a datetime struct that we could reuse everywhere ?  ``` cpp   datetime_t t = print_job_timer.duration();    /*   Example usage:   int d = t.days();       h = t.hours(),       m = t.minutes(),       s = t.seconds();   */    lcd_setstatus(t.toString());   SERIAL_ECHO_START;   SERIAL_ECHOPGM(MSG_PRINT_TIME " ");   SERIAL_ECHOLN(t.toString()); ```
