DateTimeFormat error for Chilean Time

[tomascharad]

(node v.0.12.7)
On chrome's V8 the output of the following code:
date = new Date('Mon Jun 15 2015 21:43:11 GMT-0300 (CLT)')
formatter = Intl.DateTimeFormat('En-us', { hour: 'numeric', hour12: false })
formatter.format(date)
Is "21".

However if I do the same on a node console I obtain '20'.

In Chile we've faced a change of our "Winter time" and this might be causing this issue.

Maybe there is something needed to be updated in the Intl module?

I believe its a discrepency in the timezone parsing. From chrome js console

date = new Date('Mon Jun 15 2015 21:43:11 GMT-0300 (CLT)')
Mon Jun 15 2015 20:43:11 GMT-0400 (Eastern Daylight Time)

It seems to be picking up the 'CLT' (which is actually GMT-0400).
From node:

 > date = new Date('Mon Jun 15 2015 21:43:11 GMT-0300 (CLT)')
Mon Jun 15 2015 20:43:11 GMT-0400 (Eastern Daylight Time)

seems to be using the 'GMT-0300' string rather than recognizing 'CLT'

@dnakamura maybe you meant (GMT -0300) on your second code block, right?

Anyway, I don't seem to get the (Eastern Daylight Time) on chrome, I get the same output than the one I'm writing below, which might be caused by you being in a different time zone than mine.

Mon Jun 15 2015 21:43:11 GMT-0300 (CLT)

@tomascharad Ah apparently I got confused. chrome and node seem to be in agreement parsing "Mon Jun 15 2015 21:43:11 GMT-0300 (CLT)" into "Mon Jun 15 2015 20:43:11 GMT-0400 (Eastern Daylight Time)" . Are you running chrome and node on the same machine?
Also apparently I'm wrong. They changed CLT to be GMT-0300 (I didn't think you could do that).

[tomascharad]

Look, here is the full log of the actions on chrome:

date = new Date('Mon Jun 15 2015 21:43:11 GMT-0300 (CLT)')
Mon Jun 15 2015 21:43:11 GMT-0300 (CLT)
formatter = Intl.DateTimeFormat('En-us', { hour: 'numeric', hour12: false })
Object {resolved: Object}
formatter.format(date)
"21"

And on Node:

date = new Date('Mon Jun 15 2015 21:43:11 GMT-0300 (CLT)')
Mon Jun 15 2015 21:43:11 GMT-0300 (CLT)
formatter = Intl.DateTimeFormat('En-us', { hour: 'numeric', hour12: false })
{}
formatter.format(date)
'20'

Also, just for having more background, if I do on Chrome:

new Date()
Thu Aug 13 2015 09:21:45 GMT-0300 (CLT)

and then on Node:

new Date()
Thu Aug 13 2015 09:22:55 GMT-0300 (CLT)

May be fixed by #25855 if the timezone data was in ICU 55

[srl295]

@tomascharad can you try the upgrade procedure in https://github.com/joyent/node/wiki/Intl#updating-timezone-data ?

[tomascharad]

@srl295 Could you please let me know where should I change ICU_TIMEZONE_FILES_DIR?

[srl295]

Set it in the environment. With set or setenv before node starts.

@tomascharad sorry for the slow confirmation. It is due to the tz version. In the latest released node which has ICU 55 it seems to be working:

$ env TZ=America/Santiago node
> process.version
'v3.3.0'
> process.config.variables.icu_ver_major
'55'
> date = new Date('Mon Jun 15 2015 21:43:11 GMT-0300 (CLT)')
Mon Jun 15 2015 21:43:11 GMT-0300 (CLT)
> formatter = Intl.DateTimeFormat('En-us', { hour: 'numeric', hour12: false })
{}
> formatter.format(date)
'21'

Above I discuss how to update the tz data. If it's not working, please reopen nodejs/node#2372 or a new issue. Thanks!
