The date’s and/or time’s are one or more hours off, how do I fix this?
Firstly, make sure your Timezone is set correctly for Wordpress. Change this by going to Settings > General and scroll down to “Timezone”.
Next make sure that the source you’re pulling the event data from, has the same timezone. When you’re using Google Calendar to grab your events for example, there’s an option to set the timezone for the events.
Lastly you can set the extra time option in the shortcode. This value is in seconds, so set it to 7200 to increase all time’s by 2 hours for example.
