c++ - 将本地时间转换为 time_t (C++)

Question

我在 C++ 上创建 date() 函数 http://aliarth.lt/date.cpp我在 localtome_to_time() 转换方面遇到了一个问题。有谁知道 local_time 变量如何:

int time_integer = 12345;
time_t time = (time_t)time_integer;

tm *local_time = localtime(&time);
local_time->tm_year = 100;
local_time->tm_mon = 10;
local_time->tm_mday = 1;

转换为time_t？

Answer 1

尝试mktime ，这是它的签名:

time_t mktime (struct tm * timeptr);

Returns the value of type time_t that represents the local time described by the tm structure pointed by timeptr (which may be modified).
