Daylight Savings Time problem

[songest]

Boss, Moderators

Noticed that old posts are now dated 1 hr later than what it was a day ago.
Had something gone wrong at the server end because of DST ?

The same question has been asked twice a year for the last 12 years. :p

No there is nothing wrong with the server. It's because 1 am occurs at different times in different time zones.

Boss,
Different time zones... that I understand.

However, am confused on how vBulletin displays the time after DST.

Allow me to elaborate...
All posts got advanced by 1hr, including times in User CP.
The 24hr timeclock between reputation point actions becomes confusing.
eg if u had last upz someone at 5:00pm yesterday, it now shows the previous upz time as 6pm. However, u don't have to wait till 6pm today to upz someone again (if u go by 6pm + 24hrs), u can still upz at 5pm.

The time is out of sync only for a few hours until all the automatic DST scripts on the various servers catch up with each other.

The one hr forward DST kicked in as reported at 2:29am reported below:

http://www.sammyboyforum.com/showpost.php?p=10626261&postcount=26193

It is now 9 hrs later at 11:30am Sing time and the forum is still showing 12:30pm. Auto scripts haven't kick in yet and is it possible to reduce the delay?

Dst shld occur on Sun 2am Newyork time.
There is a problem somewhere... perhaps with a server kicking in the dst correction early?

I am providing feedback so that whatever that caused it (maybe the scripts) can be fixed.

There is nothing wrong with the scripts. It will sort itself out as the various DST scripts sync.

How to explain this:

Someone posted at 2:29am Sunday singapore time (see my first post today) but the forum already displayed it as 3:29am. If this is not DST already kicking in (bringing it forward 1hr), then what is it?

If it is indeed DST kicking in, it is way too early for DST to be kicking in even for PST time where the servers are located.
The scripts logic may not have a problem but the time it is invoked may be early.

Or maybe it is a lazy hazy Sunday and my mind wasn't working well :confused:

Because there is double compensation based on what you select in http://www.sammyboyforum.com/profile.php?do=editoptions

My personal setting had always been "DST corrections always off" yet I do see the DST "1hr forward" in posts by users as well as the forum time that is at the centre bottom of the page.

Maybe you can help advise what's the correct setting and since most users are based in GMT+8, make that setting as the default.

I hope I am not being seen as intruding. Just like to provide the feedback and data points to surface the root cause.

Whatever setting you're using you don't have to change anything. It will come right after all the various time zones have are past the daylight saving transition date.

As I stated earlier, all 24 time zones should have crossed the 9th Mar 2 am point in time by now and the everything should be back to normal.

Yes. I know that after enough time had elapsed (in this case all 24 timezones past the switching time), the forum times will be back to normal.

I am still puzzled why DST kicks in early as in my first post.
Forumer first noticed that it kicked in on Sun 2:39am Sing time.
His post was done at that time but forum displays it as one hour ahead at 3:39am.

So is kickin time dependent on:

- First time zone DST +1hr forward kicks in, eg New Zealand is GMT+13.

- Kickin time is independent of where the PST servers is located, because if it is dependent, it is inconsistent with the forumer observation.

ps had tried to google for vbulletin DST bug but did not really find something useful.

In order to figure out exactly what is going on, the script that controls what is displayed has to be dissected to find out exactly which clock it is referencing and how it goes about working out when it should switch over.

It's hardly a productive pursuit since we all know it will come right within a few hours.

If it bugs you that much, I'll extract the code and send it to you for debugging.

Yes, I agree that our time can be put to more productive use.
I was just hoping that it is sometime simple like a config parameter or a setting change. I do notice that if I choose "DST corrections on" during the transition period, it actually advanced the display time by +2 hrs and not +1, double-compensation.

Just for the record, the transition period (where time is +1) happens 2am or earlier and got corrected by 7pm Sun Sing time, so it is 19 hrs or more. I personally saw that it was not corrected at 6pm but was corrected at 7pm.

It is glad to see you guys having thoughts on this issue. I will like to share my experience where i am at North Amercia Continent. My GMT Timing was -5. It doesnt really matter where the transition period falls in at anytime as long it does synchronize in hearsay couple of hours. Of all mine logging in this forum, all the timing displays falls neatly and crystal, that's about it. I will just be sure all postings on forum was display at my times but of cos if it dun then i will have a issues. I wouldnt understand my own posting dates, timing and those user cp rep system as well.

Fact is my profile timing was correct, thats the essential matter for different GMT user. I wouldnt want the default setting on GMT +8 , tats so unfriendly.
During my last winter storms, yes the transition period synchronize was bad cos our communications lines was disrupted, everyone else was so messy. Maybe we can see cats and dogs having sex? Lolx. But then after couple of weeks, everything was put in order then is okay. Matter is i dun have any issues on this daylight savings timing at all thou it falls in together couple of hours later ritefully. Essentially was the display time in the forum was correct on my ends whenever logging it. I hope this will give you guys some insights on it.

Good day to you guys:p

[georgemagnum]

Is it true that a good thing to come out of this daylight savings is that u can get to up/zap more, relatively? :D

[songest]

Bro georgemagnum,
Haha, touching matters that are close to your heart :)

From my personal observation, answer is No, your upz/zap cycle is still exactly 24hrs from your last upz/zap even though the forum clock advances +1hr.

My speculation is that the forum system has many clocks, clock for displaying post time, clock for displaying User CP time, clock for your PM message time, etc.... and they may not be all in sync during the transition.


As for bro uberzone input, thanks for your data point at GMT-5 timezone.
The transition supposed to be kick in on Sunday 2am New York time, not sure you were awake to see it. U may login many times during the day, but if it ain't the right time, u may not see the transition.

Anyway, this is history now.

The next DST -1hr rollback will occur on 2 Nov 2014 2am New York time.
If u happen to be bonking, pls choose to start your 1hr bonking session at 1am, because by the time it reaches 2am, the clock will rollback to 1am lah... so u can tell FL haven't start yet and go another round :p:D

[georgemagnum]

Lols bro .... U r interesting .... R u a time watcher in real life? :D
To a certain extent, I'm truly amazed how technical u became in view of this time thingy .... I'm only concern when I need to communicate with some friends overseas ...... :D
