"Adding an RTC is surprisingly expensive, once you’ve factored in batteries, area and componentry and would have pushed us above our target price. You can add one yourself using the GPIO pins if you’re after an interesting electronics project."
"we were very surprised to find how expensive RTC was. Maybe for a later version – we expect many people will just be leaving theirs plugged in, anyway"
