获取系统正常运行时间 [英] Getting System Up-time

问题描述

我无法确定系统正在运行多长时间。我现在太累了，但没有什么可做。我使用GetTickCount（）获得毫秒，但我必须转换他们人类可读的格式。我尝试这样的，但我得到奇怪的结果。

I'm having trouble to determine how long system is running. I'm just too tired for now, but have nothing to do. I used GetTickCount() to get Milliseconds, but I have to convert them human readable format. I tried something like this but I get strange results.

void GetUpTime(DWORD Tick) //GetTickCount() argument.
{
    wchar_t temp[256] = {0};
    ZeroMemory(tmpBuff, sizeof(tmpBuff));

    wsprintfW(temp, L"%uh %um %us", Tick/60, Tick/60*60, Tick/60*60*60);
    lstrcpyW(Time, tmpBuff);
}

我想这里，Tick / 60 =秒，Tick / 60 * 60 =分钟，Tick / 60 * 60 * 60 =小时。但我需要像：1h 5m 36s不是整个对话。
谨慎。

as I guess here, Tick/60 = seconds, Tick/60*60 = minutes and Tick/60*60*60 = hours. but I need something like: 1h 5m 36s not the whole conversation. Regards.

推荐答案

Tick / 60 * 60 与（Tick / 60）* 60 相同的东西，这显然不是你想要的。您可能表示 Tick /（60 * 60）。

Tick/60*60 means the same thing as (Tick/60)*60, which is clearly not what you want. You likely meant Tick/(60*60) instead.

DWORD seconds = Tick / 1000;  /* Milliseconds -> seconds */
DWORD minutes = seconds / 60; /* Seconds -> minutes */
DWORD hours = minutes / 60;   /* Minutes -> hours */

/* Adjust seconds and minutes to leave only the remainder. */
seconds %= 60;
minutes %= 60;

wsprintfW(temp, L"%uh %um %us", hours, minutes, seconds);
