I'm taking this code as reference for my flash MT29F4G01ABAFDWB

I'm using the MT29F4G01ABAFDWB flash memory to implement FATFS, and I'm referring to a piece of code that includes a function called hdr_get_epoch in the journal.c file.

In the code, you have a function hdr_get_epoch, and I'm curious about where the magic number used in this function is defined or used. Could you explain where you put that magic number in your code?
where in you code you have stored that magic number in your flash
