#include <stdio.h>#include <time.h>#include <stdint.h>intmain(void){time_t epoch=0;printf("%jd seconds since the epoch began\n",(intmax_t)epoch);printf("%s",asctime(gmtime(&epoch)));} Possible output: 0 seconds
在标头 <ctime> 定义 typedef /* 未说明 */ time_t; 足以表示时间的算术类型。 虽然标准中没有给出定义,但是该类型几乎总是整数类型,表示自 1970 年 1 月 1 日 00:00 UTC 以来所经过的秒数(不计闰秒),对应 POSIX 时间。 参阅 time 返回自纪元起计的系统当前时间 (函数) localtime 转换纪元...
