1，標(biāo)準(zhǔn)時間準(zhǔn)換成時間戳

int standard_to_stamp(char *str_time)??
{??
??????? struct tm stm;??
??????? int iY, iM, iD, iH, iMin, iS;??

??????? memset(&stm,0,sizeof(stm));??
??????? iY = atoi(str_time);??
??????? iM = atoi(str_time+5);??
??????? iD = atoi(str_time+8);??
??????? iH = atoi(str_time+11);??
??????? iMin = atoi(str_time+14);??
??????? iS = atoi(str_time+17);??

??????? stm.tm_year=iY-1900;??
??????? stm.tm_mon=iM-1;??
??????? stm.tm_mday=iD;??
??????? stm.tm_hour=iH;??
??????? stm.tm_min=iMin;??
??????? stm.tm_sec=iS;??

??????? /*printf("%d-%0d-%0d %0d:%0d:%0d\n", iY, iM, iD, iH, iMin, iS);*/?? //標(biāo)準(zhǔn)時間格式例如：2016:08:02 12:12:30
??????? return (int)mktime(&stm);??
}??

2，時間戳轉(zhuǎn)換成標(biāo)準(zhǔn)時間

typedef struct times
{
??????? int Year;
??????? int Mon;
??????? int Day;
??????? int Hour;
??????? int Min;
??????? int Second;
}Times;

Times stamp_to_standard(int stampTime)
{
??????? time_t tick = (time_t)stampTime;
??????? struct tm tm;?
??????? char s[100];
??????? Times standard;

??????? //tick = time(NULL);
??????? tm = *localtime(&tick);
??????? strftime(s, sizeof(s), "%Y-%m-%d %H:%M:%S", &tm);
??????? printf("%d: %s\n", (int)tick, s);?


??????? standard.Year = atoi(s);
??????? standard.Mon = atoi(s+5);
??????? standard.Day = atoi(s+8);
??????? standard.Hour = atoi(s+11);
??????? standard.Min = atoi(s+14);
??????? standard.Second = atoi(s+17);
?? ?
??????? return standard;
}

3,如何獲取系統(tǒng)標(biāo)準(zhǔn)時間

time_t rawtime ;?

struct tm * timeinfo;?

time ( &rawtime );?

timeinfo = localtime ( &rawtime );?

其中：

int Year = timeinfo->tm_year+1900;

int Mon = timeinfo->tm_mon+1;

其余日，時，分，秒都不變。

4,如何獲取系統(tǒng)當(dāng)前時間戳

?time_t now;?????????????????????????????????????????????????????????????????????????????????????????????????????????????????????
?int unixTime = (int)time(&now)；
