Timezone support for moment.js

Matt Johnson-Pint

@mattjohnsonpint

Probably, you should go back to where those are generated and make sure they include a numeric offset from UTC in them. If that's not possible, then you have some string replacement to do - but you will indeed be limited and imposing your own assumptions.

Also worth noting, that string looks like it's in RFC2822 format. That spec does indeed define certain time zone abbreviations, but they are obsoleted - carried over from the earlier RFC822 format. We have an open item to add built-in support for this older format, in moment/moment#2530

i am getting this error Moment Timezone found America/Vancouver from the Intl api, but did not have that data loaded.

Hello, in the docs for parsing the ambiguities we have to pass the offset along with the time, moment.tz("2012-11-04 01:00:00-05:00", "America/New_York"); anyone know how do we get the different offsets and different TZ's for that region? for example: for "America/Chicago" I need CDT and CST along with their offsets so that I can get the appropriate dates based on user selection

Abhijit Rao

@abhijit945

Also, is there anyway to detect if the provided time is ambiguous? I need to ask the user whether they meant CST or CDT when it is ambiguous

Abhijit Rao

@abhijit945

@mj1856 Can you point me in the right direction? Dont know if I missing something here

Abhijit Rao

@abhijit945

Hmm my current option to get the different timezones under "America/New_York" is to tap into zone object (moment.tz.zone("America/Chicago")) and get the unique offsets and unique abbrs. Is there an easier way? Still cant find a way to find if time provided is ambiguous or not

Hi folks, I'm hoping someone could help me debug a problem with not getting tz data loaded.

I'm in a bit of a weird environment though. I'm running inside the Postgres plv8 extension.

I'm using a project called node-plv8 that allows me to install node modules inside plv8 so they can be required and used as normal packages (assuming they don't make use of unsafe features like xhr and such

I did an npm install moment moment-timezone, and they are available, but moment("2015-01-01T00:00:00 America/New_York") returns null whereas moment("2015-01-01T00:00:00-05:00") works

Looking in the node_modules directory, I see a builds directory that contains the -with-data* that I imagine I want, but I'm unsure how I would go about requiring that variant of it.

Daniel Einspanjer

@deinspanjer

Ah.. I see in index.js that it does a moment.tz.load(require('.data/packed/latest.json'));. I wonder if maybe that is what is tripping up the plv8 loader

Daniel Einspanjer

@deinspanjer

Oh geeze.. it looks like the tz data is loaded fine.

the problem appears to be that I'm trying to do moment("2015-01-01T00:00:00 America/New_York"). I just tested moment.tz("2015-01-01T00:00:00", "America/New_York") and that works fine.

@mattjohnsonpint

Sorry, I don't jump on Gitter often enough.... @abhijit945, See my response on your #456

@evansiroky @ssskip - Thanks. I'll merge and do a release soon

@deinspanjer - yep, we don't have any way for moment's parser to fish out a time zone id and call into moment-timezone. You have to call it directly.

I'm going to take a quick stab at moment/moment-timezone#208

if that's a mistake for some reason, let me know, haha

if i create a moment with moment(1494595195,'X') it return a valid one, but when i set default timezone moment.tz.setDefault(America/Los_Angeles) for example and create same moment, it return an invalid Date

Matt Chandler

@mchandleraz

I'm stuck on a problem and would really appreciate some help.

I'm trying to use moment-timezone to schedule an event based on the users time zone. ie, User lives in Denver and should receive a push notification at a given time, regardless of the servers time. I have the users time zone and their chosen delivery time/date. No matter what I do, I can't get it to work. I know I'm missing something small, but this is killin' me lol

Matt Johnson-Pint

@mattjohnsonpint

@mchandleraz - not sure how to help you. "I can't get it to work" isn't a very good description of the problem. Paste a code snippet here, or ask (with supporting details) on StackOverflow. Thanks.

@midori0507 - I wasn't able to reproduce that. It works for me. (I assume you meant to put quotes around the time zone id)

Prithwiraj Sinha

@Pritzomania

Hi, Is there a way to check if a timezone identifier e.g. 'America/Chicago' is valid using moment timezone ?

The thing I am trying to do is this - If the timezone identifier provided is valid, use it otherwise fallback to a default timezone identifier value. And for that I am not seeing any straightforward way of doing it. Please help.

Matt Johnson-Pint

@mattjohnsonpint

@Pritzomania

if (!moment.tz.zone('America/Los_Angeles')) {
  // zone doesn't exist, or is not loaded.
} else {
  // zone exists and is loaded.
}

How do you stop moment-timezone adjusting times for daylight saving that have already been adjusted? London times entered are having the hour incremeneted

Peter Bailey

@pea

Think it might’ve been because I was using a unix timestamp

Matt Johnson-Pint

@mattjohnsonpint

@pea - you'd have to show me some example code

@sraja83_twitter

i have date moment.tz().toISOString()

value is 2017-06-16T13:10:02.180Z

how do i convert unix timestamp

Matt Johnson-Pint

@mattjohnsonpint

@sraja83_twitter - You don't need moment-timezone for that. That's just equivalent to moment().toISOString(), or moment.utc().toISOString().

If you want the current unix timestamp in seconds, that's moment().unix(), or in milliseconds that's moment().valueOf(), or just +moment()

If you meant how to go from the ISO string to unix time, then parse it first, as in moment("2017-06-16T13:10:02.180Z").unix() or moment("2017-06-16T13:10:02.180Z").valueOf() or +moment("2017-06-16T13:10:02.180Z")

How do i load timezone data to moment-timezone when I am using it in the server side?

@runnererr_twitter

Hi everyone, any chance timezones via .format('z') using moment-timezone are localised? An example, CET in English, but MEZ in German.

Matt Johnson-Pint

@mattjohnsonpint

@runnererr_twitter - nope. Our abbreviations come from IANA. You'll only find localized forms in CLDR data. Though even there, time zone abbreviations are grosly under-represented.

jbgithub

@jbgithub

Hello, I'm just looking to contribute. Here is a regular expression to parse the timezone from a date/time string. It works with the new and old format strings.

"date.toString() or date.toTimeString()".replace(/^.* (\([A-Za-z ]+\)|[A-Z]{3}).*$/, '$1').replace(/^.*?\(([A-Z])[a-z]+ ([A-Z])[a-z]+ ([A-Z])[a-z]+\)$/, '$1$2$3');

Credit goes to "Mootools More" Date module but I had to modify the first RE since it didn't work with the new string format.

Hey guys, I do not know where to ask. But I have a doubt, when I am creating a moment date using moment() and moment.tz() with my actual zone the dates differs by 6 hours, is this behaviour normal?
