代码:
#include<unistd.h> #include<time.h> #include<sys/time.h> int main() { int n = time(0); printf("time:%d\n",n); struct timeval tv; gettimeofday(&tv,NULL); printf("gettimeofday:%u,%u\n",tv.tv_sec,tv.tv_usec); time_t t; time(&t); struct tm *pTime; pTime = gmtime(&t); printf("gmtime:%04d-%02d-%02d,%02d:%02d:%02d\n",pTime->tm_year,pTime->tm_mon,pTime->tm_mday,pTime->tm_hour,pTime->tm_min,pTime->tm_sec); pTime = localtime(&t); printf("localtime:%04d-%02d-%02d,%02d:%02d:%02d\n",pTime->tm_year+1900,pTime->tm_mon+1,pTime->tm_mday,pTime->tm_hour,pTime->tm_min,pTime->tm_sec); return 0; }
运行结果:
time:1350457789 gettimeofday:1350457789,751874 gmtime:0112-09-17,07:09:49 localtime:2012-10-17,15:09:49
