time: misleading "zoneinfo.zip: no such file or directory" error when trying to load non-existent timezone #20969

What did you do?

> cat main.go
package main

import (
	"fmt"
	"time"
)

func main() {
	tz, err := time.LoadLocation("America/New_York")
	fmt.Printf("New_York %q %q\n", tz, err)
	tz, err = time.LoadLocation("America/New_Yaark")
	fmt.Printf("New_Yaark %q %q\n", tz, err)
}
> cat Dockerfile
FROM alpine
RUN apk add -U tzdata
COPY main /usr/bin/
ENTRYPOINT ["/usr/bin/main"]

go build -o main
docker build .
docker run ea1f31431e4d

What did you expect to see?

New_York "America/New_York" %!q(<nil>)
New_Yaark "UTC" "can't find timezone America/New_Yaark or something"

What did you see instead?

New_York "America/New_York" %!q(<nil>)
New_Yaark "UTC" "open /home/dieter/code/go/lib/time/zoneinfo.zip: no such file or directory"

note that when I run it on my host which does have a zoneinfo.zip I get:

go run main.go
New_York "America/New_York" %!q(<nil>)
New_Yaark "UTC" "cannot find America/New_Yaark in zip file /home/dieter/code/go/lib/time/zoneinfo.zip"

The text was updated successfully, but these errors were encountered:

Not a regression from Go 1.8 (or any other prior release), so targeting Go 1.10 for consideration.

I don't think it's a good idea to get rid of the part of the error message that says where it was looking to find the answer (which zip file path). You want it to say both things? Failed to find New_Yaark and also the zip file path?

Dieterbe · 2017-07-10T16:58:05Z

i'm not sure TBH. to be clear, is it perfectly normal to have situations where only a few timezones are installed, and where it can only know for sure that a tz doesn't exist if it can check against a zoneinfo.zip file?

ALTree · 2017-07-11T07:47:43Z

@Dieterbe the alternative would be to embed the whole IANA Time Zone database in the binary(?)

I agree we could try to print a better error, though (even if the current one is technically correct).

bradfitz · 2017-07-11T18:37:35Z

@ALTree, some discussion of that is in #20629 (comment).

Dieterbe · 2017-07-11T19:12:05Z

can somebody answer:

to be clear, is it perfectly normal to have situations where only a few timezones are installed, and where it can only know for sure that a tz doesn't exist if it can check against a zoneinfo.zip file?

(i hope that question did not come across snarky or sarcastic. I just need clarity on that before I can think of suggestions for improvement)

bradfitz · 2017-07-11T19:30:10Z

@Dieterbe, oh, I see what you're suggesting now. That if, say, /usr/share/zoneinfo exists on disk and is not empty, that it's the only source of truth and that the zip file shouldn't be used as a backup (and thus the error message of its non-existence would never occur).

That's a possibility. I don't believe the intent of the current code is to blend two sources of information (zoneinfo dir and zip), but just to try the zip if the file on disk doesn't exist. IIRC, currently the code just tries to open a single file under /usr/share/zoneinfo and doesn't try to determine whether sibling files exist.

agnivade · 2018-06-30T19:52:44Z

Analysis: The code directly checks for a file under /usr/share/zoneinfo without checking for the directory. And it only accepts a non syscall.ENOENT error as a valid error to hold in the error variable as it iterates through the list of zoneSources. That is the reason why the error where it was unable to access /usr/share/zoneinfo/<file> was getting eaten up.

So we need to check for the existence of a zoneinfo dir first, and then check for the file inside the dir if it exists and return a similar non ENOENT error ("cannot find <file> in <dir>") like others.

Only thing is, I will need to copy over a minimal implementation of syscall.Stat (to check for dir existence) to prevent dependency on os package. Luckily, for plan9 and windows, the .zip file is the only zoneSource so nothing to do over there.

Will send a CL.

govardhanpagidi · 2019-07-20T00:07:28Z

May I know what is the fix for this issue?

I ran into the same issue, go runtime fails to convert time if the timezone is "Asia/kolkata" but works with "Asia/Calcutta"

it runs of my local machine(go version 1.11.4 , Ubuntu 18.X) but not on server (Ubuntu 16.x).

I appreciate your help !!

ianlancetaylor · 2019-07-20T00:30:46Z

@pagidi This issue was closed months ago. For help with Go, please see https://golang.org/wiki/Questions.

On Ubuntu timezone information comes from files in the /usr/share/zoneinfo directory. So if a timezone works on one system but not another, it means that the two systems have different zoneinfo files.

tsuz · 2019-08-22T17:04:28Z

@pagidi

ADD https://github.com/golang/go/raw/master/lib/time/zoneinfo.zip /usr/local/go/lib/time/zoneinfo.zip

is what made it work for me full gist

govardhanpagidi · 2019-09-09T04:56:35Z

Thanks @tsuz

But My problem seems different.
It works in my development machine since it has go runtime
I don't have go run time in the server (it runs as .deb executable), but the go application expects zoneinfo file in the location /usr/local/go/lib/time/zoneinfo.zip

Is there way, we can give path in the Go program to look for the zoneinfo.zip???

agnivade · 2019-09-09T06:15:20Z

Please look into the documentation - https://golang.org/pkg/time/#LoadLocation.

LoadLocation looks in the directory or uncompressed zip file named by the ZONEINFO environment variable, if any, then looks in known installation locations on Unix systems, and finally looks in $GOROOT/lib/time/zoneinfo.zip.

I would suggest to update the zone information on your remote server. If that does not work, use the ZONEINFO variable.

In future, for Go related questions please use the forums in https://golang.org/wiki/Questions. Closed issues are not monitored. Thanks.

govardhanpagidi · 2019-09-09T09:28:53Z

Thanks for the help! @agnivade

Though I have used ZONEINFO variable it didn't work, am I missing something here?

$ locate zoneinfo
/usr/share/zoneinfo/right/Asia/Brunei
/usr/share/zoneinfo/right/Asia/Calcutta
/usr/share/zoneinfo/right/Asia/Chita
/usr/share/zoneinfo/right/Asia/Choibalsan
/usr/share/zoneinfo/right/Asia/Chongqing
/usr/share/zoneinfo/right/Asia/Kolkata

it means zoneinfo is located in user/share/zoneinfo/

$export ZONEINFO=/usr/share/zoneinfo/

Still I see application throws below Error.
cannot find "Asia/Kolkata" in zip file /usr/local/go/lib/time/zoneinfo.zip

mvrhov · 2019-09-09T13:13:38Z

Because you use the wrong directory in your export
$export ZONEINFO=/usr/share/zoneinfo/right
