I took 3 pictures.

Picture 1 shows a different solderless breadboard with the following connections:

1. Power is being taken from Vdd and Vss (black and white wire from the SX52 to the solderless breadboard). 

2. 3 orange wires go from RA.0 - RA.2 into the DS1302 pins 7,6 and 5 respectively. 

3. 1 yellow wire goes from RA.3 (however any unused RA pin would have the same bad effect - RA.3 - RA.7) to the white Serial LCD RX pin. 

4. A black ground wire is going to the black Serial LCD ground pin. 

5. +5v (red wire) is going to the DS1302 (pin 1). 

6. Ground (black wire) is going to the DS1302 (pin 4). 

 

Picture 2 

Shows the Time Display is correct (12:00:xx AM) AND the Serial cable IS plugged in to the LCD. 

 

 

Picture 3

 

Shows the Time Display is not correct (00:00:xx AM) AND the Serial cable IS NOT plugged into the LCD. 

 

 

I hope this makes it more clear. I am at a loss for figuring this strange occurance out.
