Looks like real time clocks are allowed to be running while you are in the deployer.  I think this is brand new (they used to be disallowed, and there is apparently a typo in the conditional requirements specification numbers).  Seems to me like the allowable current limit is about 3 or 4 orders of magnitude more than necessary.   I have seen data sheets for RTC's that need only a few hundred nA to keep time.  Am I missing something?
