- add the string length as an explicit parameter to get_time_string() 

- remove casts when the same type is used on both sides
- expand hours_buffer[] to fit the range of hours in an 'int'
- add a work around for the sprintf() truncation checker that fails
  to detect that 'minutes' and 'seconds' have a small range
