[En-Nut-Discussion] Synching Calldirect using NutOS

[Harald Kipp]

Hi Andre,

Timing is a bad chapter in Nut/OS. Initially a second counter
had been implemented, but I had to learn, that the patches
for running Nut/OS without 32kHz crystal do not update this
counter. Another bad story is, that NutGetTickCount is almost
unusable for timing calculations unless you spoil the code
with lots of ifdefs.

Well, the new function NutGetSeconds() should be a better
basis for adding time(), gmtime() and all the other goodies.
As long as an accuracy of about 1 second is sufficient,
this should be easy to implement now.

On the protocol side NTP is quite complicated, I'd prefer
a simplified SNTP. But nothing is available right now, AFAIK.

How come I receive all worms from MS then. :-)
