Registration question

Cheesecake · 2013-09-30 02:53:04

I just now created my account after a lot of research on that registration question.
There seems to be a bug. Where i live, it is currently week number 39 on my machine, but its Sunday night and i am UTC-06:00. I tried many different hashes to the question and when i finally answered it right, the only thing i had changed was that i advanced the clock to October 1st so it was week 40.

Welcome to Arch Linux. Any chance you could post or email me some examples. I would not have expected this bug to show up except on the last day of the month/year.

Awebb · 2013-09-30 10:40:45

It's the last day of a month, so... :-)

It is now. When I posted (last night) it was not yet the last day of the month here on the West coast of North America; and no part of the world was yet into October.

Awebb · 2013-09-30 13:52:01

Your post happened Today 04:58:42 over here (GMT+1 with DST) and the server is in Germany. Dateception?

Cheesecake, can I have another slice can you please open a bug report? You need a separate account for the bug tracker, so you have to register there too.

ewaller · 2013-09-30 14:40:50

Awebb,

What I am wondering is what happens if someone is in a different month than it is either in Germany or UTC. For example, as I post this, The Western Pacific is into next Month. Europe is not there yet. I'll get there in about 16 hours.

At the time I posted last night, the entire world was still in September. I am having trouble envisioning why the OP had to tweak his date to next month. I want to understand.

This is what i had tried

and this is what worked (after i had tweaked the date)

date -u +%W$(uname)|sha256sum|sed 's/\W//g'

I changed the date to the first of next month because it was in the next week. I assume i could have picked any day from September 30 to October 6 but i picked a day closer to the middle of the week to be on the safe side.

I thought so, I always asked myself, why October was the important part, but I dismissed the thought as "better safe than child support".

cfr · 2013-10-06 00:04:58

I currently get week 39 - not week 40 - even though it is October 6th. Am I missing something?

karol · 2013-10-06 00:18:50

@Cheesecake
It used to be %W but https://bugs.archlinux.org/task/32649

From man date:

%U     week number of year, with Sunday as first day of week (00..53)
%V     ISO week number, with Monday as first day of week (01..53)
%W     week number of year, with Monday as first day of week (00..53)

%V returns 40.

Shouldn't all machines return the same value because of the -u flag, regardless of local settings? Assuming the user set his time zone right. I don't understand why you expect a problem at the end of a month.

karol · 2013-10-06 00:58:02

$ date -u
Sun Oct  6 00:56:22 UTC 2013
$ date -u +%V
40

cfr, please post your output.

Edit: Typo.

It's because the posts above (mostly) used %W not %V. I get the expected results with %V.

$ date -u
Sul  6 Hyd 01:01:29 UTC 2013
$ date -u +%V
40

EDIT: I also don't understand quite why failures are expected given that the -u flag is passed.

the server is in Germany right?
when i posted this

Germany   early Monday morning
US         late Sunday night
Germany   %W   ==>  40
US         %W   ==>  39
Germany   %U   ==>   40
US         %U   ==>   40

because it was on Sunday night the %U would have made it work for me in the US and maybe this was what i was supposed to do. But, I first thought the server used %W and the only problem was because his hash was different from mine because he was in a different week.
If i was supposed to use %U then that just delays the problem to Saturday night registering people.

Germany   early Sunday morning
US         late Saturday night
Germany   %W   ==>  39
US         %W   ==>  39
Germany   %U   ==>   40
US         %U   ==>   39

cfr · 2013-10-13 22:51:17

Right. But the question is why the -u flag doesn't avoid that problem.

gpunkt · 2013-10-23 16:01:36

Hello there,

Could someone be so kind and give some tipps on the solution OR point out the answer?
A friend of mine, familar with linux but having some problems with the configuarion of arch, is trying to get into the .org forums of archlinux because the dotDE aren't that active.
And second question: WHY is this question there in the first place? to scare of newbies? This question wasn't there back when I joined, it seems the forum wants to be "elite"...

the question is %W(andsoon) at the moment but it should be %V as we've worked out... but maybe it's part of the question.
I can understand this action against spammers but the question should work.

Some people still have problems with registering: https://bugs.archlinux.org/task/37630

Is there a way I can help with this?
There's also a chance that people are having issues with copy-pasting and not with the forum registration question itself.

Scimmia · 2013-11-06 17:19:40

That bug was because the author didn't have his UTC set correctly and was running it right before the week switched. Because of that, it was giving him the wrong week number. Completely user error and would only be a problem for a few hours a week anyway.

I got the same answer as he did and I run

date -u +%V$(uname)|sha256sum|sed 's/\W//g'

minutes after he posted the report.

How can I make sure I have UTC set correctly?

Overall, it seems to be working...

Scimmia · 2013-11-06 17:25:11

timedatectl should tell you what UTC is. As of right now, current is "Wed 2013-11-06 17:24:41 UTC"
