[Help Wanted] How can I tell if my car's block heater is working properly?

Is there any way to tell if the block heater is working properly after it's been plugged in? I feel like I've had it plugged in overnight, but the time to warm up the car the next day hasn't decreased. I'm not sure if the block heater is broken.
