v3.0.13
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)
