Please include the values of all variables used.

Environment:

OSX Node.js 8.4.0

Both the browser and the OS are important to us, particularly if you have an unsual environment like an IOT application.

Other information that may be helpful:

• The time zone setting of the machine the code is running on
• The time and date at which the code was run
• Other libraries in use (TypeScript, Immutable.js, etc)

If you are reporting an issue, please run the following code in the environment you are using and include the output:

console.log( (new Date()).toString())
console.log((new Date()).toLocaleString())
console.log( (new Date()).getTimezoneOffset())
console.log( navigator.userAgent)
console.log(moment.version)

console.log( (new Date()).toString())
Thu Aug 17 2017 17:09:27 GMT+0800 (CST)
console.log((new Date()).toLocaleString())
2017-8-17 17:09:27
console.log( (new Date()).getTimezoneOffset())
-480
console.log( navigator.userAgent)
Mozilla/5.0 (Macintosh; Intel Mac OS X 10_12_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/62.0.3178.0 Safari/537.36
console.log(moment.version)
2.18.1

Ensure your issue is isolated to moment. Issues involving third party tools will be closed unless submitted by the tool's author/maintainer.
