Is there a standard format for RTCs? I don't know what to write to the
RTC 32-bit register to set it. I came up with my own hh:mm:ss.xxx
format for storage in a 32 bit register, but I wonder if it's
compatible? After all, I certainly hope it's not based on ms from some
date because it would only store 49.xxx days then.
