Paid More Than 15 Minutes Ago

We’re trying to set up a scheduled export that exports orders that were paid at least 15 minutes ago.

We have an order filter set up where _paid_date <= {15 Minutes Ago}, and the following custom PHP:

add_filter( “woe_compare_field_cast_to_type”, function($type, $field, $operator, $value, $public_fieldname){
if( $public_fieldname == “_paid_date” ) $type = “date”;
return $type;
},10,5);

add_filter(‘woe_settings_validate_defaults’, function ($settings) {
$settings = json_encode($settings);
$settings = str_replace( ‘{15MinutesAgo}’, date(“Y-m-d H:i”, strtotime(“-15 minutes”)), $settings);
$settings = json_decode($settings, true);
return $settings;
} );

This doesn’t seem to be working, however.

Orders that were paid less than 15 minutes ago are still appearing in the export. If strtotime(“-15 minutes”) is changed to strtotime(“-1200 minutes”), though, which suggests perhaps a timezone issue with the comparison?

Any help you could give would be much appreciated.
