Date Format for application not for whole environment

I'm facing an issue where I need to change the date format for an application to DD-MM-YYYY. 

I can't set this in Environment Configuration as there are other applications with different users that are using YYYY-MM-DD format. 

Is there an easy way to do this for just this application without defining the format everywhere there is a date?

Unfortunately, the answer is no. To accomplish this, you need to use your own formatting function for dates, and also parse the dates from input fields.

Hi Quentin,

You can define the format in the Site Properties. However you might have to use the date format conversion like in the  eg: FormatDateTime(var,Site.EgDateFormat)
