Date Interface default?

[timothycoxon]

So I've got a workflow that is designed to run either manually or on a schedule. 

In said workflow I have a macro that uses a "date interface" to select a date.

The idea is that when the workflow runs as a scheduled task it would default to today or if it was run manually then you would be able to select which date you would run the workflow on.

Problem I am facing is that it seems to retain the last selection made in the interface.

Is there a system variable that is set when a workflow is run on a schedule? Is it possible to set the date interface to default to today?

Any help much appreciated.
