blinkInterval causes crash if it overflows when multiplying by 2

This code should be updated to verify the blinkInterval is valid before creating a Duration object:

What would be the desired behavior in the case of overflow? Max value or no blinking?

Edit: Moving the * 2 to the declaration would probably fix it for "no blinking".

I personally don't have a preference between not blinking vs blinking once every few weeks :)
