+ * The Retu RTC is essentially a partial read-only RTC that gives us Retu's

+ * are sane to compensate for any horrible drift (on account of not being able
+ * to set the clock to anything).
+ *
+ * Days are semi-writeable. Namely, Retu will only track 255 days for us
+ * consecutively, after which the counter is explicitly stuck at 255 until
+ * someone comes along and clears it with a write. In the event that no one
+ * comes along and clears it, we no longer have any idea what day it is.
