CCS/MSP432P4111: Show the system date and hour in the MSP432P4111 LCD display

Have a look at the MSP432P4111 Out-of-Box demo- this shows how to write characters to the LCD. 

The rtc_c_caldnear_alarm_interrupt example shows you how to write to the register. The RTC_C_getCalendarTime(void) API is used to pull the current time. The datastructure it returns is of type RTC_C_Calendar, whose structure is:

typedef struct _RTC_C_Calendar
{
uint_fast8_t seconds;
uint_fast8_t minutes;
uint_fast8_t hours;
uint_fast8_t dayOfWeek;
uint_fast8_t dayOfmonth;
uint_fast8_t month;
uint_fast16_t year;
} RTC_C_Calendar;
