Moment.js和时刻时区将当前时间分隔为秒，分钟和小时

Question

I have referenced two scripts into my project:

<script src="http://momentjs.com/downloads/moment.js"></script>
<script src="http://momentjs.com/downloads/moment-timezone-with-data.js"></script>

And now the code part:

<script>
    $(document).ready(function () {

        var now = moment(); // current timestamp, using your machine's time zone

        var nowNY = now.tz('America/New_York'); // converted to NY time zone
        console.log("Current time in NYC: " + nowNY.format());
    });
</script>

In console this displays the following:

Current time in NYC: 2018-12-13T03:59:13-05:00

Now I just need to extract the part with the 03 (hours) 59 (minutes) and 13 (seconds)

But I'm not sure how to do this, can someone help me out?

Answer 1

Simply use format('HH:mm:ss')

This is the most robust display option. It takes a string of tokens and replaces them with their corresponding values.

You can use HH for 00-24 hours, mm for 0-59 minutes and ss for seconds.

Here a live sample:

 var now = moment(); // current timestamp, using your machine's time zone var nowNY = now.tz('America/New_York'); // converted to NY time zone console.log("Current time in NYC: " + nowNY.format('HH:mm:ss'));

Adding to @VincenzoC 's answer (and as he correctly added in his comment ), the moment library has specific Getters for hours, minutes, seconds if you want to use. Like this ( as dictated in the moment docs )

var now = moment(); console.log(now.hours());

Or if you want to stay with the format function you can use it like this

now.format('HH'); now.format('mm'); now.format('ss');
