How to connect VMA100 Arduino Atmega328 with VMA302 LCD shield to VMA301’s DS1302 clock?

Due to lack of documentation, I am having difficulty connecting the clock to the Arduino board with the 16x2 display shield. As for jumpers, I connected the Clock’s VCC to Arduino 5V, Gnd to Gnd, CLK to A5, and DAT to A4.

Question 1: Where do I connect the Clock’s RST onto the Arduino?
Question 2: When I run the sketch found on the VMA301 page, it calls for a Time.h header but I cannot find any Time.h that works with the latest 1.8.5 compiler. Can you tell me where I can find Time.h?

First of all I would suggest that you connect one of the shields. Make it work first. Then switch to the other shield. Make it work first and finally combine them.

I did connect my RST to pins below

#define CE_PIN 5 // Chip Enable
#define IO_PIN 6 // Input/Output
#define SC_PIN 7 // Serial Clock

But I also see that those pins wil not be availble when mounting the LCD shield.

As for your second question:

I did use this library for the real time clock

Thank You Adriaan! I connected my three clock wires to A3, A4, and A5 which correspond to pins 17, 18, and 19. The clock is working! Thanks for your help!
