正如一些转换那些unix时间戳的网站所说，
2013/05/07 05:01:00 (yyyy/mm/dd, hh:mm:ss) is 1367902860.
我在C++中的处理方式与日期不同。
这是代码:
time_t rawtime;
struct tm * timeinfo;
int year=2013, month=5, day=7, hour = 5, min = 1, sec = 0;
/* get current timeinfo: */
time ( &rawtime ); //or: rawtime = time(0);
/* convert to struct: */
timeinfo = localtime ( &rawtime );
/* now modify the timeinfo to the given date: */
timeinfo->tm_year = year - 1900;
timeinfo->tm_mon = month - 1; //months since January - [0,11]
timeinfo->tm_mday = day; //day of the month - [1,31]
timeinfo->tm_hour = hour; //hours since midnight - [0,23]
timeinfo->tm_min = min; //minutes after the hour - [0,59]
timeinfo->tm_sec = sec; //seconds after the minute - [0,59]
/* call mktime: create unix time stamp from timeinfo struct */
date = mktime ( timeinfo );
printf ("Until the given date, since 1970/01/01 %i seconds have passed.\n", date);
产生的时间戳是
1367899260, but not 1367902860.
这里有什么问题？即使我更改为hour-1或hour + 1，它也不匹配。编辑:是的，如果我加1到一小时，它的工作原理。以前也增加了1分钟。
最佳答案
您必须使用timegm()而不是mktime()，仅此而已。因为mktime是本地时间，而timegm是UTC/GMT时间。
