Item.Date issue with timezone (UTC vs PDT)

[homingli]

In an Item for the feed that I'm pulling from...

<pubDate>Tue, 19 Jul 2016 13:14:13 PDT</pubDate>

On my local laptop with local time set to PDT, I don't have a problem:
2016-07-19 13:14:13 -0700 PDT

On my server with local time set to UTC, I have this odd timezone problem:
2016-07-19 13:14:13 +0000 PDT

Where exactly are you seeing the issue? Is it in the time values in the Feed structure?

[homingli]

I don't control the feed, but here is a scrubbed version of it...

<?xml version="1.0" encoding="UTF-8"?>
<rss version="2.0">
  <channel>
    <title>Title</title>
    <link>link</link>
    <link rel="alternate" href="url.rss" type="application/rss+xml" title="title"/>
    <title type="text">Title</title>
    <language>en-us</language>
    <pubDate>Wed, 20 Jul 2016 00:04:18 PDT</pubDate>

     <item>
      <title type="text">title</title>
      <link>link</link>
      <pubDate>Tue, 19 Jul 2016 13:14:13 PDT</pubDate>
      <guid>guid</guid>
      <description>description</description>
     </item>
  </channel>
</rss>

Test Code:

$ cat test.go
package main

import (
  "github.com/SlyMarbo/rss"
  "fmt"
)

func main() {
    feed,_ := rss.Fetch(url) // rss url scrubbed
    fmt.Println(feed.Items[0].Date)
}
$ go run test.go
2016-07-19 13:14:13 +0000 PDT

I'm not entirely sure what's going on here, but I can't see where it's going wrong. What happens if you call feed.Items[0].Date.UTC()?

[homingli]

Really strange behavior, no change to the time, but just says UTC rather than PDT:
2016-07-19 13:14:13 +0000 UTC

Didn't really dig into it, not sure if it's related to golang/go#4001 but the issue is closed.

[SlyMarbo]

I'm afraid I don't know what to do here. Sorry :(

[homingli]

Do you think you can reproduce this so to confirm it's not just me that's experiencing this issue? Thanks!

[SlyMarbo]

Yeah, I'm getting the same behaviour. I suspect it's an issue with package time.

[SlyMarbo]

Closed until we can confirm this is an issue in rss.

[homingli]

@SlyMarbo The behavior is expected. I need to supply location and parse in location in order to achieve the expected result. See referenced issue golang/go#16517.

package main

import (
  "time"
  "fmt"
)

func main() {
    t, _ := time.Parse(time.RFC1123, "Tue, 26 Jul 2016 03:34:46 PDT")
    fmt.Println(t)
    loc, _ := time.LoadLocation("America/Los_Angeles")
    t, _ = time.ParseInLocation(time.RFC1123, "Tue, 26 Jul 2016 03:34:46 PDT",loc)
    fmt.Println(t)
}

output

2016-07-26 03:34:46 +0000 PDT
2016-07-26 03:34:46 -0700 PDT

How can I do that with your package?

[SlyMarbo]

Huh, I was not expecting that. I'll see what I can do.

[SlyMarbo]

Ah, it seems you can get the time package to give the intended behaviour if you override time.Local manually before using the rss functionality: https://play.golang.org/p/rWZfKkDGRI
