Help with a HT1621 LCD Module, 6 Digit 7 segment

I am trying to display a 6 digit integer on this HT1621 LCD display. I was given the attached example code as a starting point, but it is a timer code.

I found this forum [
which somehow creates a 6 digit integer, but I don't understand it.

Any help? Could someone please create the whole script for me as I am new to coding.

much appreciated.
