Wildfire RTC not setting

Hi, I'm trying to set the RTC on the wildfire but I'm having some trouble. I pulled most of this code from the Angular Clock example code but it isn't working. One issue I found is that the rtc.setDateTime call in the Angular example code doesn't match the function signature in MCP7941x.h (you'll see that the .h file has
void setDateTime ( byte second, byte minute, byte hour, byte dayOfWeek, byte dayOfMonth, byte month, byte year );

While the Angular Clock code attempts to call this without passing in dayOfWeek
rtc.setDateTime(tm.Second,tm.Minute,tm.Hour,1,tm.Day,tm.Month,tm.Year);

Even after correcting for this I still can't seem to set the RTC. Or maybe I'm setting it but just unable to pull the time from it? Here's my code, any assistance would be appreciated.

#include <Wire.h>
#include <Time.h>
#include <WildFire.h>
#include <MCP7941x.h>

MCP7941x rtc=MCP7941x();
tmElements_t tm;
WildFire wf;

void show_time_tm(char *msg){
  Serial.println(msg);
  Serial.println (F("DW DD-MM-YYYY"));
  Serial.print(tm.Wday, DEC);
  Serial.print(F("  "));
  Serial.print(tm.Day, DEC);
  Serial.print(F("-"));
  Serial.print(tm.Month, DEC);
  Serial.print(F("-"));
  Serial.println(tm.Year+2000, DEC);
  Serial.println(F("HH:MM:SS"));
  Serial.print(tm.Hour, DEC);
  Serial.print(F(":"));
  Serial.print(tm.Minute, DEC);
  Serial.print(F(":"));
  Serial.print(tm.Second, DEC);
  Serial.println();
}

void setup(){
  Serial.begin(9600);
  Wire.begin();
  wf.begin();
  delay(1000);
  
  rtc.enableClock(); 
  byte ss, mm, hh, dW, dM, MM, YY;
  ss = 0;
  mm = 0;
  hh = 11;
  dW = 6;
  dM = 1;
  MM = 12;
  YY = 15;
  rtc.setDateTime(ss,mm,hh,dW,dM,MM,YY);
  rtc.getDateTime(&tm.Second,&tm.Minute,&tm.Hour,&tm.Wday,&tm.Day,&tm.Month,&tm.Year);
  show_time_tm("RTC Clock set");
}

void loop () {
  show_time_tm("RTC Clock Time:");
  delay(5000);
}

Running this I don't get the date and time I put in, and the time doesn't advance. Instead I get the following output, with all sorts of values that don't make sense (like the 45th hour of the 25th month) and never change. What am I missing?

RTC Clock set
DW DD-MM-YYYY
7  45-25-2165
HH:MM:SS
45:85:85
RTC Clock Time:
DW DD-MM-YYYY
7  45-25-2165
HH:MM:SS
45:85:85
RTC Clock Time:
DW DD-MM-YYYY
7  45-25-2165
HH:MM:SS
45:85:85
