Consistent date / time date of the client using JavaScript (including time zones)

Question

My question relates to this quote from a date guide in JavaScript:

Note: parsing date strings using a date constructor (and Date.parse, they are equivalent) is strongly discouraged due to browser differences and inconsistencies.

new Date('2016-04-14')for the user was Wed Apr 13 2016 17:00:00 GMT-0700 (US Mountain Standard Time)on which he was supposed to use .toUTCString().

How to handle this if users are in many different time zones?
