Hmm, I guess I'll have to rewrite my code if nobody else has any ideas.
Edit: I managed to figure out how to adjust the time using the Adafruit library, but now in trying to rewrite the coding, I am getting another error:
RTClib\RTClib.cpp.o: In function `date2days':
C:\Arduino-1.0.3\libraries\RTClib/RTClib.cpp:26: multiple definition of `i'
Project_1.cpp.o:(.bss.i+0x0): first defined here
c:/arduino-1.0.3/hardware/tools/avr/bin/../lib/gcc/avr/4.3.2/../../../../avr/bin/ld.exe: Disabling relaxation: it will not work with multiple definitions
c:/arduino-1.0.3/hardware/tools/avr/bin/../lib/gcc/avr/4.3.2/../../../../avr/bin/ld.exe: Warning: size of symbol `i' changed from 1 in Project_1.cpp.o to 2 in RTClib\RTClib.cpp.o
I haven't the faintest clue how to fix this.
I am wondering if it might be easier just to figure out what is going on with the Karlsen library...
