Defined in header <ctime>
char* ctime( const std::time_t* time );

std::asctime(std::localtime(time))を呼び出したかのように、カレンダーをローカル時間にしてから、テキスト表現にエポックからの経過時間を与えられたに変換します。結果の文字列の形式は次のとおりです

Original:

Converts given time since epoch to a calendar local time and then to a textual representation, as if by calling std::asctime(std::localtime(time)). The resulting string has the following format:

印刷する時間を指定してstd::time_tオブジェクトへのポインタを返します Original: pointer to a std::time_t object specifying the time to print The text has been machine-translated via Google Translate. You can help to correct and verify the translation. Click here for instructions.

値を返します

日付と時刻のテキスト表現を保持する静的ヌル終端の文字列へのポインタ。文字列はstd::asctimeとstd::ctime間で共有することができ、これらの機能のいずれかを呼び出すたびに上書きされる可能性があります.

Original:

Pointer to a static null-terminated character string holding the textual representation of date and time. The string may be shared between std::asctime and std::ctime, and may be overwritten on each invocation of any of those functions.

ノート

この関数は、静的データへのポインタを返し、スレッドセーフではありません。また、std::tmとstd::gmtimeと共有することができる静的なstd::localtimeオブジェクトを変更します。 POSIXでは、この関数は廃止されたとマークして、代わりにstd::strftimeお勧め.

Original:

This function returns a pointer to static data and is not thread-safe. In addition, it modifies the static std::tm object which may be shared with std::gmtime and std::localtime. POSIX marks this function obsolete and recommends std::strftime instead.

挙動は、time_t型の値は文字列で、その結果より長い25文字（例：年間10000）のために定義されていないかもしれません

Original:

The behavior may be undefined for the values of time_t that result in the string longer than 25 characters (e.g. year 10000)
