Problem with the invoice dates

Hi,

I am facing a problem with the dates that the system use in the confirmation emails an in the invoice form.

Let me give you an example:

in the invoice the system gives me

Code Payment method Checkin Checkout
d1bdae6f SR_PAYMENT_METHOD_0 18-06-2016 28-06-2016

But in the customer has chosen:

Checkin 19-06-2016
Checkout 29-06-2016

From Joomla configuration I have change the server time zone to Athens Europe.

Can you please help in order to fix the date difference?

Thank you

I am using Solidres 0.8.1.Stable
