node.js - 是否有任何类似于 c# 上的 Environment.TickCount 的 NodeJs 类/函数？

Question

此代码在 c# 上运行

int x = Environment.TickCount;

docs for Environment.TickCount

Gets the number of milliseconds elapsed since the system started. TickCount cycles between Int32.MinValue, which is a negative number, and Int32.MaxValue once every 49.8 days.

TickCount will increment from Zero to (2147483647) for approximately 24.9 days, then jump back to (-2147483648), which is a negative number, then increment back to zero during the next 24.9 days.

We can use int result = Environment.TickCount & Int32.MaxValue; to make it rotate between (0) and (2147483647) for every 24.9 days

我想要 NodeJS 中的等效方法，它会产生相同的结果。
我在 NodeJS 上进行了搜索 npmjs但没有找到类似的功能

Answer 1

os.uptime()是最接近您需要的方法

Returns the system uptime in number of seconds

NodeJS docs
但这是一个有效的问题，即上述方法的最大限制是多少。？
在 NodeJS 中，最大安全整数是 Number.MAX_SAFE_INTEGER即 9007199254740991 .基本上是 289583309.373 years .所以我想我们将不得不假设这是所述方法的最大值。
如果你想要 c# 的功能 TickCount ，您将需要创建自己的自定义方法，可能如下所示:

// this method will cycle between 0 and 2147483647
function TickCount() {
    const miliseconds_elapsed = os.uptime() * 1000; // convert the time in miliseconds
    return miliseconds_elapsed % 2147483647;
}

// this method will cycle between -2147483648 to 2147483647
// note: it will not start from 0
function TickCount() {
    const miliseconds_elapsed = os.uptime() * 1000; // convert the time in miliseconds
    return (miliseconds_elapsed % 4294967296) - 2147483648;
}

// this method will cycle between -2147483648 to 2147483647
// note: it will start from 0 goes to 2147483647 
// then comes back to -2147483648 and starts the cycle
function TickCount() {
    const miliseconds_elapsed = os.uptime() * 1000; // convert the time in miliseconds
    if (miliseconds_elapsed <= 2147483647) {
        return miliseconds_elapsed;
    }
    return ((miliseconds_elapsed - 2147483648) % 4294967296) - 2147483648;
}
