我正在尝试编写一个将时间和日期转换为纪元秒的函数,它适用于没有通常的 time_t 库函数的小型系统。我在下面有这段代码,但计算有点不对,有人能看出什么问题吗?
long getSecondsSinceEpoch(int h, int m, int s, int day, int month, int year) {
int i,leapDays;
long days;
long seconds;
const static DAYS_IN_MONTH[] = {31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31};
leapDays = 0;
days = (year - 1970) * 365;
for (i = year; i>1970; i--){
if ((i%4)==0) {
leapDays++;
}
}
days += leapDays;
for (i = 1;i < month;i++) {
days += DAYS_IN_MONTH[i - 1];
}
days += day;
seconds = days * 86400;
seconds += (h * 3600);
seconds += (m * 60);
seconds += s;
return seconds;
}
