@semeniako Wow the code is lot more complicated than I imagined. The simplest would to contact the writer of the code as he could tell you quickly. I would look at where the hour_pos, min_pos and seconds variables are being set and adjust accordingly.
@Makuna quick question. I am using your neopixel libary with RX pin. Is there an alternative to hooking the eso-01 to an arduino serially such as softserial on ESP ?
