Date object not returning the correct locale time

[james33]

I'm running node 0.6.14 on a Joyent machine (OS is a varient of Solaris). The timezone is set to US/Central, but the Date object in node doesn't seem to recognize this. Below are the outputs of a few different console.logs:

process.env.TZ: 'US/Central'

new Date(): 'Mon, 09 Apr 2012 04:45:28 GMT'

new Date().toLocaleString(): 'Mon Apr 09 2012 05:45:28 GMT+0100 (CST)'

The current US/Central time is actually 'Sun Apr 08 2012 23:45:28 GMT -0500 (CDT)'. Is this a bug or am I doing something wrong?

[Matt Patenaude]

Hmm, European CST is GMT+1, it could be using that instead (in spite of the US/ bit there). Try changing to (for example) 'America/Chicago' and see if you get different results?

I still get the same result.

And what if you pick a completely different timezone, e.g., America/Los_Angeles?

I get GMT+0100 (PST) with that.

[Matt Patenaude]

Just to make sure environmental variables aren't getting messed with somehow, try running this:

echo "console.log((new Date()).toLocaleString());" | TZ='America/Los_Angeles' node

Should print out a locale string at GMT-0700 (PDT). If it doesn't, then I'd defer to someone else who's more knowledgeable about the internals of Node's Date object than myself. :)

It returns Mon Apr 09 2012 23:01:04 GMT+0100 (PST)

You should report this to V8 because I'm 99% sure it's a bug. To wit,
this is the V8 shell on a Linux or OS X system:

$ TZ='America/Los_Angeles' out/ia32.release/shell -e 'print(new
Date().getTimezoneOffset())'
420
$ TZ='Europe/Amsterdam' out/ia32.release/shell -e 'print(new
Date().getTimezoneOffset())'
-120

And this is on a Solaris system:

$ TZ='America/Los_Angeles' out/ia32.release/shell -e 'print(new
Date().getTimezoneOffset())'
-60
$ TZ='Europe/Amsterdam' out/ia32.release/shell -e 'print(new
Date().getTimezoneOffset())'
-60

If I have some time to kill, I'll look into fixing it myself.
