Without a real time clock you should be more concerned about true
random numbers than _warnings_ like:

I assume here that such a platform as also other contrainsts than just
the RTC.  Having good and unpredictbale random numbers is crucial to
the security of the key.  Creating DSA signatures also requires a good
RNG as well as some other subsystems.

A warning is just a warning and does not aks you to press a key.
