I have to calculate a sale end time relative to today,
I have the sale end time variable in this format {%d/%m/%Y %H:%M:%S} e.g.:(31/07/2016 18:27:58).
What I'm trying to do is to show ends: 8 days 06:10:29.
I can't use php code in the template because I'm using smarty 3 and I'm not an expert in smarty.
