moment has updated the js lib as of 06 2018    var newYork      moment tz  2014-06-01 12 00    America New York    var losAngeles   newYork clone   tz  America Los Angeles    var london       newYork clone   tz  Europe London     newYork format          2014-06-01T12 00 00-04 00 losAngeles format       2014-06-01T09 00 00-07 00 london format           2014-06-01T17 00 00 01 00   if you have freedom to use Angular5   then better use datePipe feature there than the timezone function here  I have to use moment js because my project limits to Angular2 only

As long as you have initialized moment-timezone with the data for the zones you want  your code works as expected   You are correctly converting the moment to the time zone  which is reflected in the second line of output from momentObj format     Switching to UTC doesn t just drop the offset  it changes back to the UTC time zone   If you re going to do that  you don t need the original  tz   call at all   You could just do moment utc     Perhaps you are just trying to change the output format string   If so  just specify the parameters you want to the format method   momentObj format  YYYY-MM-DD HH mm ss     Regarding the last to lines of your code - when you go back to a Date object using toDate    you are giving up the behavior of moment js and going back to JavaScript s behavior   A JavaScript Date object will always be printed in the local time zone of the computer it s running on   There s nothing moment js can do about that   A couple of other little things    While the moment constructor can take a Date  it is usually best to not use one   For  now   don t use moment new Date      Instead  just use moment     Both will work but it s unnecessarily redundant   If you are parsing from a string  pass that string directly into moment   Don t try to parse it to a Date first   You will find moment s parser to be much more reliable  Time Zones like MST7MDT are there for backwards compatibility reasons   They stem from POSIX style time zones  and only a few of them are in the TZDB data  Unless absolutely necessary  you should use a key such as America Denver

The question is a little obscure  I ll do my best to explain this  First you should understand how to use moment-timezone  According to this answer here  TypeError  moment   tz is not a function  you have to import moment from moment-timezone instead of the default moment  ofcourse you will have to npm install moment-timezone first    For the sake of clarity   const moment require  moment-timezone    import from moment-timezone   Now in order to use the timezone feature  use moment tz  date string moment     time zone    visit https   momentjs com timezone  for more details   This function will return a moment object with a particular time zone  For the sake of clarity   var newYork  moment tz  2014-06-01 12 00    America New York     this code will consider NewYork as the timezone      Now when you try to convert newYork  the moment object  with moment s toDate    ISO 8601 format conversion  you will get the time of Greenwich UK  For more details  go through this article https   www nhc noaa gov aboututc shtml  about UTC  However if you just want your local time in this format  New York time  according to this example   just add the method  utc true   with the arg true   to your moment object  For the sake of clarity   newYork toDate    will give you the Greenwich  UK  time   newYork utc true  toDate    will give you the local time  according to the moment tz method arg we specified above  it is 12 00 you can ofcourse change this by using moment     In short  moment tz considers the time zone you specify and compares your local time with the time in Greenwich to give you a result  I hope this was useful

I needed to have timezone information in my date string  I was originally using moment tz dateStr   America New York   toString    but then I started getting errors about feeding that string back into moment   I tried the moment tz dateStr   America New York   toDate    but then I lost timezone information which I needed   The only solution that returned a usable date string with timezone that could be fed back into moment was moment tz dateStr   America New York   format

Since momentjs has no control over javascript date object I found a work around to this     x000D   x000D  const currentTime   new Date        x000D  const convertTime   moment currentTime  tz timezone  format  YYYY-MM-DD HH mm ss    x000D  const convertTimeObject   new Date convertTime   x000D   x000D   x000D    This will give you a javascript date object with the converted time
