C将char []转换为时间戳;

Question

我有char date [] =“2011-04-01”;它如何在C或C ++中转换为时间戳？

Answer 1

警告： strptime 是一个POSIX - 功能（可能无法在操作系统“Windows”平台上通过 time.h 获得）。

#include <time.h>

struct tm time;
strptime("2011-04-01", "%Y-%m-%d", &time);
time_t loctime = mktime(&time);  // timestamp in current timezone
time_t gmttime = timegm(&time);  // timestamp in GMT

Answer 2

试试这个：

char date[] = "2011-04-01";
date[4] = date[7] = '\0';
struct tm tmdate = {0};
tmdate.tm_year = atoi(&date[0]) - 1900;
tmdate.tm_mon = atoi(&date[5]) - 1;
tmdate.tm_mday = atoi(&date[8]);
time_t t = mktime( &tmdate );
