Military Time Code coach problem

Question

Why is this not passing all the cases?

#include <stdio.h>
#include <string.h>

int main() {
char ntime[10];
int i=0, j, k, l;

fgets(ntime,10,stdin);
//printf("%s",ntime);

l = strlen(ntime);

for(j=0;j<l;j++){
if(ntime[l-j-1] == 'A'){
for(i=0;i<l-3;i++){
printf("%c",ntime[i]);
}
return 1;
}
}
if(ntime[1] == ':'){
switch(ntime[0]){
case '1' :
printf("13");
break;
case '2' :
printf("14");
break;
case '3' :
printf("15");
break;
case '4' :
printf("16");
break;
case '5' :
printf("17");
break;
case '6' :
printf("18");
break;
case '7' :
printf("19");
break;
case '8' :
printf("20");
break;
case '9' :
printf("21");
break;
default :
break;
}
for(i=1;i<l-3;i++){
printf("%c",ntime[i]);
}
return 1;
}else if(ntime[2]==':'){
switch(ntime[1]){
case '0' :
printf("22");
break;
case '1':
printf("23");
break;
case '2':
if(ntime[3]=='0' && ntime[4]=='0'){
printf("24");
}else{
printf("00");
}
break;
default :
break;
}
for(i=2;i<l-3;i++){
printf("%c",ntime[i]);
}
return 2;
}
return 0;
}
