Unix timestamp - Thời gian Unix

1

Khái niệm quen thuộc trong hệ thống Unix và lập trình PHP. Thời gian Unix, là hệ thống nhằm diễn tả một điểm trên trục thời gian, theo trục thời gian nó sử dụng số giây kể để xác định thời điểm, với điểm gốc từ thời điểm 00:00:00 ngày 1/1/1970 (UTC).

Ví dụ lúc 00:00:00 - 1/1/2017 có giá trị timestamp là 1483228800; Có nghĩa là tính từ 00:00:00 - 1/1/1970 đến 00:00:00 - 1/1/20171483228800 giây.

Trong PHP sử dụng hàm time() để lấy timestamp hiện tại. Để đổi thời gian dạng timestamp sang các định dạng ngày tháng khác dùng hàm date()

2

Hàm time() trong PHP cung cấp cho bạn tất cả thông tin bạn cần về date và time hiện tại. Nó không yêu cầu tham số nhưng trả về một integer.

sử dụng saga

We can't really recommend a way to start root sagas however we can certainly explain better the effect. I think it's probably worth creating a dedicated documentation page.

your examples 1.

// single entry point to start all Sagas at once
export default function* rootSaga() {
  yield [

Deffered in jquery

First: You cannot use $.Promise(); because it does not exist. A deferred object is an object than can create a promise and change its state to resolved or rejected. Deferreds are typically used if you write your own function and want to provide a promise to the calling code. You are the producer of the value.

A promise is, as the name says, a promise about a future value. You can attach callbacks to it to get that value. The promise was "given" to you and you are the receiver of the future value. You cannot modify the state of the promise. Only the code that created the promise can change its state.

Examples:

  1. (produce) You use deferred objects when you want to provide promise-support for your own functions. You compute a value and want to control when the promise is resolved.
