Just update your new version but it’s cost another problem is once we set the fix departure date for 1 day tour,
once customer book now and set the date example from today 16/4/2019 and the end date also 16/4/2019.
How to set when customer set 16/4/2019 and automatically end date is follow by the server time and set to 17/4/2019?
Actually, this is a feature that has been included in the WP Travel since the old versions and is not introduced in the latest version.
Your case is the case of 2 days 1 night trip since, if the trip will be ending on the next day, the duration should be fixed with the night included and the date will fix likewise.
However, if you still want the feature to set the time according to the server time, you need to hire our professional developer. To hire a developer, please refer to the given link : https://wptravel.io/hire-our-customizer/
