From http://en.cppreference.com/w/cpp/language/constexpr: A constexpr specifier used in an object declaration implies const. However, We can not change from static constexpr const char* TIME_FORMAT = "%a %b %d %I:%M:%S %Z %Y"; to static constexpr char* TIME_FORMAT = "%a %b %d %I:%M:%S %Z %Y"; The compiler complains: In file included from json/formatter.cc:22:0: json/formatter.hh:132:42: error: deprecated conversion from string constant to ‘char*’ [-Werror=write-strings] static constexpr char* TIME_FORMAT = "%a %b %d %I:%M:%S %Z %Y"; Since, unlike const, constexpr does not modify a type. It just applies to an object (or function), and incidentally implies const to the top-level type.
