Eduardo Arias 23a341eb6a Calculate sizes of strftime buffers based on format strings
- Leverage std::size to determine buffer size at compile time.
- Simplified 'TimeMon::evaluate' implementation as it was using strftime
  to get the month, convert the string to int, and then decrement it by
  one to make it zero based. This same value is already available in
  the 'struct tm' previously generated with the call to localtime_r (and
  where the month is already zero-based)
