Back to the Future

We can't just time-travel around without first making sure our code is pretty and columns are aligned. And keeping lines with at most 80 characters should help if we ever need to review the code while we're stuck in the past. This is my first challenge. I tried being creative and even did a bit of research, so I hope you enjoy it.

Input

#include  // Includes time machine code
#include  // Includes DeLorean code

// Defines bool
typedef enum {
	false,
	true
} bool;

// Creates objects
TimeTravel TimeMachine; // Tracks power input, allows jumping in time
DeLorean Vehicle; // Manages the storage, display and input of time, tracks
// speed

long TimeDestination = -2682276364; // Destination time, POSIX
long TimePresent = -2682276364; // Present time
long TimeLast = -2682276364; // Last departed time

unsigned float SpeedCurr = 0.0; // Current speed, in miles per hour
unsigned float SpeedTarget = 88.0; // Target speed

unsigned float PowerCurr = 0.0; // Current power, in gigawatts
unsigned float PowerTarget = 1.21; // Target power

char
loop ()
{
	// Updates local time variables
	TimeDestination = Vehicle.getTime (dtime);
	TimePresent = Vehicle.getTime (ptime);
	TimeLast = Vehicle.getTime (ltime);

	// Updates local speed and power variables
	SpeedCurr = Vehicle.getSpeed ();
	PowerCurr = TimeMachine.getPower ();

	// Get ready statuses
	bool TMReady = TimeMachine.getReady ();
	bool VReady = Vehicle.getReady ();

	// Calculates travel time, in seconds
	long TimeOffset = TimeDestination - TimePresent;

	// Checks speed, power and ready statuses
	if (SpeedCurr >= SpeedTarget && PowerCurr >= PowerTarget && TMReady && VReady) {
		// Prompts for a time travel of given length, checks if no error returned
		if (!TimeMachine.travel (TimeOffset)) {
			Vehicle.setTime (ltime, TimePresent); // Updates last time with
			// time as of before traveling
			Vehicle.setTime (ptime, TimeDestination); // Updates present time with
			// time as of after traveling
		} else {
			return 1;
		}
	}

	return 0;
}

char
setup ()
{
	// Begin objects, store errors
	char errTM = TimeMachine.begin ();
	char errV = Vehicle.begin ();

	if (!errTM && !errV)
		return 0;

	return 1;
}

char
main ()
{
	// Runs setup, store error
	char err = setup ();

	// Loops as long as no error
	while (!err) {
		// Run loop, update error
		err = loop ();
	}

	return 1;
}
