07 objects encapsulate an integral number that represents milliseconds since the midnight at the beginning of January 1, 1970, UTC [the epoch]

Ghi chú. TC39 is working on Temporal, a new Date/Time API. Read more about it on the Igalia blog. It is not yet ready for production use

A JavaScript date is fundamentally specified as the number of milliseconds that have elapsed since the , which is defined as the midnight at the beginning of January 1, 1970, UTC [equivalent to the UNIX epoch]

Ghi chú. It's important to keep in mind that while the time value at the heart of a Date object is UTC, the basic methods to fetch the date and time or its components all work in the local [i. e. host system] time zone and offset

It should be noted that the maximum

07 object [equivalent to ±8,640,000,000,000,000 milliseconds]

There are several methods available to obtain a date in various formats, as well as to perform time zone conversions. Particularly useful are the functions that output the date and time in Coordinated Universal Time [UTC], the global standard time defined by the World Time Standard. [This time is historically known as Greenwich Mean Time, as UTC lies along the meridian that includes London—and nearby Greenwich—in the United Kingdom. ] The user's device provides the local time

In addition to methods to read and alter individual components of the local date and time [such as 

const date = new Date["2020-05-12T23:50:21.817Z"];
date.toString[]; // Tue May 12 2020 18:50:21 GMT-0500 [Central Daylight Time]

Ghi chú. In browsers that support the Web Performance API's high-resolution time feature, 

const date = new Date["2020-05-12T23:50:21.817Z"];
date.toString[]; // Tue May 12 2020 18:50:21 GMT-0500 [Central Daylight Time]
date.toDateString[]; // Tue May 12 2020
date.toTimeString[]; // 18:50:21 GMT-0500 [Central Daylight Time]
date.toISOString[]; // 2020-05-12T23:50:21.817Z
date.toUTCString[]; // Tue, 12 May 2020 23:50:21 GMT
date.toJSON[]; // 2020-05-12T23:50:21.817Z
date.toLocaleString[]; // 5/12/2020, 6:50:21 PM
date.toLocaleDateString[]; // 5/12/2020
date.toLocaleTimeString[]; // 6:50:21 PM
24 can provide more reliable and precise measurements of elapsed time than 
const date = new Date[];
const [month, day, year] = [
  date.getMonth[],
  date.getDate[],
  date.getFullYear[],
];
const [hour, minutes, seconds] = [
  date.getHours[],
  date.getMinutes[],
  date.getSeconds[],
];

const date = new Date["2020-05-12T23:50:21.817Z"];
date.toString[]; // Tue May 12 2020 18:50:21 GMT-0500 [Central Daylight Time]
date.toDateString[]; // Tue May 12 2020
date.toTimeString[]; // 18:50:21 GMT-0500 [Central Daylight Time]
date.toISOString[]; // 2020-05-12T23:50:21.817Z
date.toUTCString[]; // Tue, 12 May 2020 23:50:21 GMT
date.toJSON[]; // 2020-05-12T23:50:21.817Z

date.toLocaleDateString[]; // 5/12/2020

In this case, it's important to return only an integer—so a simple division won't do. It's also important to only return actually elapsed seconds. [That's why this code uses 

const date = new Date["2020-05-12T23:50:21.817Z"];
date.toString[]; // Tue May 12 2020 18:50:21 GMT-0500 [Central Daylight Time]
date.toDateString[]; // Tue May 12 2020
date.toTimeString[]; // 18:50:21 GMT-0500 [Central Daylight Time]
date.toISOString[]; // 2020-05-12T23:50:21.817Z
date.toUTCString[]; // Tue, 12 May 2020 23:50:21 GMT
date.toJSON[]; // 2020-05-12T23:50:21.817Z
date.toLocaleString[]; // 5/12/2020, 6:50:21 PM
date.toLocaleDateString[]; // 5/12/2020
date.toLocaleTimeString[]; // 6:50:21 PM
26, and not 
const date = new Date["2020-05-12T23:50:21.817Z"];
date.toString[]; // Tue May 12 2020 18:50:21 GMT-0500 [Central Daylight Time]
date.toDateString[]; // Tue May 12 2020
date.toTimeString[]; // 18:50:21 GMT-0500 [Central Daylight Time]
date.toISOString[]; // 2020-05-12T23:50:21.817Z
date.toUTCString[]; // Tue, 12 May 2020 23:50:21 GMT
date.toJSON[]; // 2020-05-12T23:50:21.817Z
date.toLocaleString[]; // 5/12/2020, 6:50:21 PM
