#include <iostream>
#include <ctime>int main(int argc, char *argv[])
{struct tm timeinfo;char cur_time[] = "current time: 2021-09-06 23:50:13";// 解析时间到timeinfo中strptime(cur_time, "current time: %Y-%m-%d %H:%M:%S", &timeinfo);printf("%s\n", asctime(&timeinfo));return 0;
}
稍微复杂些的格式：
#include <iostream>
#include <ctime>int main(int argc, char *argv[])
{struct tm timeinfo;char cur_time[] = "2021年 Sep 6 Mon 23:50:13";strptime(cur_time, "%Y年 %b %d %a %H:%M:%S %Y-%m-%d %H:%M:%S", &timeinfo); size_t buf_size = 80;char buf[buf_size];strftime(buf, buf_size, "%Y-%m-%d %H:%M:%S", &timeinfo);printf("%s\n", buf);return 0;
}
