Hi @busybird15,
if you analyze the sketch from your post #4 the data you look for should be available in loop() like this (not tested!!):
now.Hour()
now.Minute()
now.Second()
Feel free to try this changed loop() in this sketch:
// CONNECTIONS:
// DS1302 CLK/SCLK --> 5
// DS1302 DAT/IO --> 4
// … Answer from ec2021 on forum.arduino.cc

Using DS1302 RTC module with Arduino | by Rahul Jain | Medium
March 3, 2020 - The line ThreeWire DatClkRst (6,7,8); create a bundle of 3 wires which will be used to initialise the object Rtc from RtcDS1302 class using the command RtcDS1302<ThreeWire> Rtc(DatClkRst); The function SetDateTime resets the date and time of the DS1302 chip. The date and time at the time of compilation of Arduino’s C code are stored in the RtcDateTime object “compiled”. The loop() method runs with a delay of 1 second.
