And please avoid using UTC….!

Yellow Swordfish.
Thanks for the quick response.
I read what was in the link, however, did not understand what I have to do to solve the problem.
What I did was just leave ajutado UTC on wordpress, which in the case for my country is UTC -3 and set my time zone to Sao Paulo.
It’s wrong what I did.
Thank you.

Hello!
I managed to get the UTC’s forum, but still poestagem is the time of 2 hours at least.
Thank you.

so your wp time zone is set to the server timezone right?  not your timezone… and its a city?

and then in your sp profile, did you set your actual timezone?

Hello!

I made all the adjustments, see the pictures.

If I did something wrong let me know.
Thank you.

Are you now saying that both your server AND your local timezones are no longer set to UTC numbers? If this is the case then what problem remains? Are new posts not coming out correctly? Don’t forget – it is new posts that are important here.

Hello Swordfish!

I am sending a picture to a new posting in SP. Note that the time is wrong.
Thank you.

Well the only other thing we have found that can continue to cause anomalies – at least that we are aware of – arr other WP plugins that might manipulate date/time data in some way. Plugins like event calendars for example – these sometimes perform timezone resets. Do you have any plugins active that may be working with time apart from SP?

Hello!
I have no plugin installed to calendar or something. I just Wishilist, Askimet, and W3 Total Cache S3FlowShield.
Thank you.

Hello!
Solved the problem.
I just created a new topic and the time is right.
Thank you.

But the last one was wrong and was also, you said, just created. So what changed please?

Hello!
Actually I have not changed anything, just created a topic after a few minutes and had the correct time.
I believe the reason was the WP Total Cache.
Thank you.

yes, you cannot cache the wp page the forum is on… you need to tell w3tc to ignore that page for ALL types of caching you are using…

outstanding… thanks for the update…
