How to pass a variable to a function?

Using char instead of string (this is in the main loop for now).

              //Extract Date and Time from stringbuffer (which is of type char)
  char timeBuffer[9];

  timeBuffer[9] = '\0';
  for (int x = 5; x < 5 + dateLength; x++) 
  {
    timeBuffer[x] = StringBuffer[x];
    Serial.print(StringBuffer[x]); //prints separate chars
  }
        Serial.println("");
        Serial.print("timeBuffer printed output is  ");    
        Serial.println(timeBuffer);

Output is

10041245
timeBuffer printed output is

Separate characters are printed, but timeBuffer is not printed even when I added a null char to the end.
