Title: PHP Timezone is Invalid Last modified: May 5, 2020 --- # PHP Timezone is Invalid * [Zanzara](https://wordpress.org/support/users/zanzara/) * (@zanzara) * [5 years, 11 months ago](https://wordpress.org/support/topic/php-timezone-is-invalid/) * I’m getting this message in my WordPress Site Health page. “PHP default timezone was changed after WordPress loading by a date_default_timezone_set() function call. This interferes with correct calculations of dates and times.” * It seems to be coming form the Ultimate Auction Pro plugin. * How can I fix this?

Could you please share below: * 1. Full plugin name * 2. Plugin version. * We doubt that you are using an old plugin and that too a pro version which we do not support any more. * [@jjk697](https://wordpress.org/support/users/jjk697/) , * Could you please share below information: * 1. Could you please share system information: PHP Version, WP Version, Mysql version and plugin name and its version. * 2. Where do you see this message? Kindly share the steps to reproduce it * Regards, * Thread Starter [Zanzara](https://wordpress.org/support/users/zanzara/) * (@zanzara) * [5 years, 11 months ago](https://wordpress.org/support/topic/php-timezone-is-invalid/#post-12816461) * Hi Nitesh, The name of the plugin is: Ultimate Auction Pro Awesome plugin to host auctions on your wordpress site and sell anything you want. Version 7.0.9 | By Nitesh Singh | Visit plugin site * [hrsms](https://wordpress.org/support/users/hrsms/) * (@hrsms) * [5 years, 10 months ago](https://wordpress.org/support/topic/php-timezone-is-invalid/#post-12846459) * Hello Nitesh, * I am having the same problem. WordPress reports this as a critical error when your plugin is active, and it stops reporting it when deactivated. It is certainly this plugin and not another. * “PHP default timezone was changed after WordPress loading by a date_default_timezone_set() function call. This interferes with correct calculations of dates and times.” * Ultimate WordPress Auction Plugin Version 4.0.6 * Thanks, Greg * [jgysenbergs](https://wordpress.org/support/users/jgysenbergs/) * (@jgysenbergs) * [5 years, 9 months ago](https://wordpress.org/support/topic/php-timezone-is-invalid/#post-13116484) * Does this break something after setting correct time zone? * [ulf_g](https://wordpress.org/support/users/ulf_g/) * (@ulf_g) * [5 years, 5 months ago](https://wordpress.org/support/topic/php-timezone-is-invalid/#post-13629238) * I have the same, or similar, experience. This plugin interferes with my My Calendar plugin and changes all the times. * So, a temporary workaround is to set the timezone for the ultimate auction plugin to the London timezone (even though I live in Sweden). This will adjust the times in the calendar to the correct start- and end time. * However, this will also have an impact on the start- and end times when adding a new auction. If I set the end time to 1 PM (13:00) – now it’s 12:24 – it will say that the auction ends in 1 hr and 35 minutes. * I’m not really sure what’s my best option here. * [harlointeractive](https://wordpress.org/support/users/harlointeractive/) * (@harlointeractive) * [5 years, 2 months ago](https://wordpress.org/support/topic/php-timezone-is-invalid/#post-14009782) * We have the same issue. This error message shows up as a “critical issue” under the wordpress site health area so you should resolve it. Can’t you configure the plugin to use the same time zone that is set by the user under the wp general settings? why would you try to set your own timezone here? just use the wordpress general setting for this or at least give the admin the option so we can fix this. * Using WP 5.6.1, Ultimate Auction 4.0.8 * [jeff41](https://wordpress.org/support/users/jeff41/) * (@jeff41) * [5 years ago](https://wordpress.org/support/topic/php-timezone-is-invalid/#post-14290014) * I am having the same problem. Is there a workaround for this? * [jeff41](https://wordpress.org/support/users/jeff41/) * (@jeff41) * [5 years ago](https://wordpress.org/support/topic/php-timezone-is-invalid/#post-14294438) * The problem appears to be the use of the date_default_timezone_set() function which WordPress heavily recommends against using because it causes so many problems. That was from the developer with another plugin the auction plugin caused problems in. According to them the timezone needs to be UTC. * I commented out the function in the ultimate-auction.php module and the php error code went away. This meant the countdown is now 7 hours out of date though as London time is 7 hours ahead. * Is there a more permanent fix for this? I like the plugin. It’s exactly what I need and well thought out. * [mikeyed](https://wordpress.org/support/users/mikeyed/) * (@mikeyed) * [4 years, 12 months ago](https://wordpress.org/support/topic/php-timezone-is-invalid/#post-14310250) * I am having the same problem and I did design a plugin that has date_default_timezone_set(‘ America/Los_Angeles’); in it. Because WordPress is way too confused over timezones and I had to correct it. Without that code, here is what happens. * When I go to dashboard -> settings -> general it shows the proper UTC time and the proper Local time yet it uses the UTC time as the default. I want to use local time and wordpress refuses so I forced the default timezone. * [traings](https://wordpress.org/support/users/traings/) * (@traings) * [4 years, 10 months ago](https://wordpress.org/support/topic/php-timezone-is-invalid/#post-14463174) * Hi, I am having the same problem and used the fix suggested by [@jeff41](https://wordpress.org/support/users/jeff41/) The problem is certainly having to compensate for the difference between UTC and local time manually. I see this problem started one year ago. Did anyone found a definite solution?
