How do I store data in char arrays and convert to int in C

Question

So I currently take a file pointer as a parameter as im reading data in a file stored as 14 00 05 where 14 is the hours 00 is the minutes and 05 is the seconds. I want to be able to convert these values to into a single int and produce the output int time = 140005

int time_conversion(FILE *file) {
    char hrs[2];
    char mins[2];
    char secs[2];
    char total[6];

    fscanf(file, " %s %s %s", hrs, mins, secs);
    strcat(total, hrs);
    strcat(total, mins);
    strcat(total, secs);
    return atoi(total);
}

The issue I'm currently having is that when I read in the char mins[2] the first char stored in char hrs[2] gets ovverun for some unkown reason. Example of output after the fprintf()

char hrs[0] = '\000'
char hrs[1] = '4'

char mins[0] = '\000'
char mins[1] = '0'

char secs[0] = '0'
char secs[1] = '5'

If you want to do it with strings:

#include <stdio.h>
#include <string.h>
#include <stdlib.h>
int time_conversion(FILE* file) {
    char hrs[3];
    char mins[3];
    char secs[3];
    char total[7];
    fscanf(file, "%s %s %s", hrs, mins, secs);
    strcpy(total, hrs);
    strcat(total, mins);
    strcat(total, secs);
    return atoi(total);
}
int main(void) {
    FILE* f = fopen("file.txt", "r");
    int wynik = time_conversion(f);
    printf("%d", wynik);
    return 0;
}
