#include <stdio.h>

// Usage: gcc -o validate timestamp_validate.c
// ./validate -f [transcript you want to validate]
// 
// EXAMPLE OUTPUT:
// ./validate -f transcript1.txt
// ? != 0:00:00.000  			//Ignore output, comparing garbage before first two timestamps are read in.
// 0:15:23:00 != 0:15:22:00     //Error - check timestamp at 0:15:23
// 0:00:00:00 != 0:22:16:00		//Error - possibly due to reloading console and previous time marker being erased
