I received this from support:
“The new wordpress update has brought some changes to date_i18n()
I believe the issue you are experiencing is due to a change in the date_i18n() function causing values to be modified via the timezone setting.
This issue does not effect the value saved into the DB, but occurs when loading and “formatting” the value.
We have a few similar bug reports at this time, and will investigate this shortly.
For now, can you please try the following fix: Edit the file “includes/api/api-helpers.php” on line 4117 and change from:
return date_i18n($format, $unixtimestamp);
to:
return wp_date($format, $unixtimestamp);”
Thank goodness for that, I though I was going mad. Exactly the same issue. All dates presented on front end a day behind but OK in back-end. Upgraded ACF and WordPress to latest versions so I don’t know which has caused this problem.
This is a football results website so is date crucial. Added dates to day and they are OK, it seems to be dates that were created prior to the upgrades. Re-saving doesn’t seem to solve it.
HELP!
