can u give me a hand with this code?

I do not know if micro (u) can, but I'll try

1) You post "dallas rtc & 8052" but your code uses a timer.
2) RTC using a time should, if even a decent performance is desired be done with timer 2 in auto reload mode, the variance from reloading in an ISR will kiil you.
3) the LCD code use movc, change to movx and make the routine point to the time converted to ASCII
