Newbie questions: timers as counters, RTC access and DNS alternatives.

Thanks to all,

well, I asked just in case and trying to learn but none of the issues seem to be 100% crucial, I mean I have already programmed most of the code really quickly so and now that I know how powerful is JS I am not going back to C. Regarding to the issues:

1. Finally I can make all the "regular" timming work only using SetTime & GetTime.
   
2. I would like to use the internal RTC so I will try to do the config in C, test it and copy/paste registers. If doesn't work I will consider to place an external RTC or just measure the offset and calibrate a non precisse timer.
   
3. As Wilberforce said DNS names are not the only way to identify nodes so I guess I will find another way: MAC, broadcasting, or something else.
   
   

Regards,
Manuel.
