var startTime, endTime : int % Declare the two variables to keep track of time.

startTime := Time.Sec % Set startTime to the number of seconds since the start of the universe (1970).
delay(5000) % Wait 5 seconds, for demonstration purposes.
endTime := Time.Sec % Set endTime to the number of seconds since the start of the universe (1970).

put(endTime - startTime) % Output the difference between startTime and endTime.


% Note: Turing rounds passed time somewhat unpredictably. It's accurate enough for most purposes, however.

import time # Import the time module, so we can use the time functions.

startTime = time.time() # Set startTime to the number of seconds since the start of the universe (1970).
time.sleep(5); # Wait 5 seconds, for demonstration purposes.
endTime = time.time() # Set endTime to the number of seconds since the start of the universe (1970).

print(endTime - startTime) # Output the difference between startTime and endTime.

# Note: In Python, time.time() returns the time since the start of the universe in seconds as a float.
# The precision can vary between machines however. It is not guaranteed to be more precise than 1 second.

long startTime = System.currentTimeMillis(); // Set startTime to the number of milliseconds since the start of the universe (1970).

// Delays in Java are more verbose than in other languages.
try {
	Thread.sleep(5000); // Wait for 5 seconds.
} catch(InterruptedException e) { // Catch an error that can (but almost never does) occur when using Thread.sleep().
	e.printStackTrace(); // If there is an error (which there shouldn't be), print the error message.
}

endTime = System.currentTimeMillis(); // Set endTime to the number of milliseconds since the start of the universe (1970).
System.out.println(endTime - startTime); // Output the difference between startTime and endTime.

// The precision of Java's System.currentTimeMillis() can vary between machines.
