Moment. JS to UTC format

In the use of Moment.js Convert to UTC Format time , We may meet 2 A little question .

If you use

('2021-11-01T19:39:00.000').utc().format();

To carry out UTC Time conversion , You will find that your input time and output time are different .

Change time zone

If as described above , In the result , We see the following figure

Input time , We actually use UTC Time for , But after the conversion is successful , We will find that 2 There is a time deviation .

The reason for this deviation is the current time of your computer .

We can see from the figure below ：

When the object is initialized , Whether it is UTC The time parameter options are false.

Therefore, there will be deviation .

If you know the input time is UTC In time , You can use the following code ：

moment.utc('2021-11-01T19:39:00.000').format();

If you initialize an object in this way , The time stamp of the object will be marked UTC Time .

format Function has no milliseconds

Smart you may see , If you use format() Function to format ISO There are no milliseconds in time .

If you want your time object to have millisecond data after formatting the output .

The method you should use is ：

toISOString()

Look at the following code ：

moment.utc('2021-11-01T19:39:00.000').toISOString()

As shown in the figure below , After the following code formats the output, there will be millisecond data ：

This is what we need to pay attention to in actual use .
