encoder for utility i am making for O.RKS , optimised for encoding XC workouts

XC_encode.py

import time 
def encode(hour,minute,second,distance):#hour from 0-9 distance meters
    hour=min(max(0,hour),9)*10000
    minute=min(max(0,minute),60)*100
    second=min(max(0,second),60)
    distance=max(min(1609.344*32,distance),0)
    return chr(hour+minute+second)+chr(int(distance))+chr(int(time.localtime().tm_year))+chr(int(time.localtime().tm_yday))
def decode(s):
    time=ord(s[0])
    dist=ord(s[1])
    hour=int(time/10000)
    minute = (int((time-hour)/100))
    second = (int((time-hour-minute)/10))
    year=ord(s[2])
    day=ord(s[3])
    return f"hour {hour} minute {minute} second {second
