[En-Nut-Discussion] Duration of the RTC's capacitor

[scostas]

Hi all:

I'm working with the Ethernut 3.0 and found that the RTC maintains the
time only for about one and half days, but I need it to last at least a
week or two, because the systems can be stored during that time, and I
need that there will be no need to set the clock again each time the
system is powered up.

Thanks in advance.
