Defined in header <time.h>
time_t mktime( tm* time );
time_ttime->tm_wdayの値を無視して、time->ydayオブジェクトとしてエポックからの経過時間にローカルカレンダー時刻に変換します。 timeの他の構成要素の値は、それらの通常の範囲に制限されません。 time->tm_isdstの負の値は、夏時間が有効であったかどうかを判断しようとしmktimeを起こす.
Original:
Converts local calendar time to a time since epoch as a time_t object, ignoring the values of time->tm_wday and time->yday. The values of other components of time are not restricted to their usual ranges. A negative value of time->tm_isdst causes mktime to attempt to determine if Daylight Saving Time was in effect.
