  Increase buffer size for the string representation of n_time
  
  ICMP timestamp is a 32-bit number. In pr_ntime(), number of minutes
  and seconds is always 2 characters wide. Max. number of hours is 4
  characters wide. The buffer size should be at least:
  
  4 + 2 + 2 + 1 (':') + 1 (':') + 1 ('\0') = 11
