Are you sure the time on your actual server (NTP) is not running behind?

You cannot, its basically a bug.

The changes made for php7 mean it will only work with whole hours, not 0.5 hours.

You cannot, its basically a bug.

It would need core code changes in multiple places I think

I'm looking at the code and comparing it to VB 4.2.3 which I assume worked, but all the code I see had hard coded multiplying the offset by 3600 (which is # of seconds in an hour 60*60) so I don't understand where partial hours come into the code.

Can anyone confirm the last version timezones worked correctly? Did they work in 4.2.4?

VB.com thread- https://www.vbulletin.com/forum/forum/vbulletin-4/vbulletin-4-questions-problems-and-troubleshooting/4375422-incorrect-time-after-update-4-2-5 (in case we get a fix.)

EDIT- I have confirmed the partial hours DO work in VB 4.2.4.

OK it seems:

$vbulletin->userinfo['tzoffset']

is being forced to be an int somewhere in VB 4.2.5.

In VB 4.2.4 it can be a float. 30 minutes would be like 4.5 and 45 minutes would be like 6.25

Still checking code for fix.

OK,

functions.php in the /includes/ directory.

Line 4503:


$tzos = intval($vbulletin->userinfo['timezoneoffset']);


If you remove intval from the code, the time works (you have to set the timezone again after making this change.

It works in the forum and posts. It does NOT work on calendar events, for some reason there are additional intval() functions in the calculator.

I'm going to look deeper into the security ramifications of removing the intval function from this line but a quick glace I see no problem.

So my final determination is to simply change

$tzos = intval($vbulletin->userinfo['timezoneoffset']);


to

$tzos = floatval($vbulletin->userinfo['timezoneoffset']);


on line 4503 of /includes/functions.php to get the time working on most of the site.

Unfortunately I don't see any way to make this a plugin, the manual edit it necessary.

Where is it displaying this? Screenshot?

[Paul M]

Its a bug.

The code was changed in multiple places due to changes in php 7.1
Unfortunately it wasnt realised that some timezones use 0.5 hours, so intval was used.

This issue wasnt noticed until now, so too late to fix.
As above, the fix would probably be to update all the changes to use floatval.

i set timezone to +5.30 but its disply +5. only
time is working fine after change from

but timezone steel not working fine

[Stingray27]

but timezone steel not working fine
More than one change
the fix would probably be to update all the changes to use floatval.

You may need to re-choose the timezone from the settings as well.

same issue like time, timezone not display +-30 and +-45

[Stingray27]

Its just a display, you are worrying about it too much, that display doesnt do anything else.
