AutoTools Date time calculation on variables

In Autotools, we can do Math on a fixed date/time, is there a way to pass a variable as date/time?

 

I have a datetime in yyyy-MM-ddTHH:mm:ss format in a variable. I pass that var to 'Add time' function with correct format. I pass 330 value as minutes to add.

The problem is, no matter what datetime I set it to, it always adds the minutes to the Current Time. Use Now is unchecked.

 

Looks like I found the issue, yyyy-MM-ddTHH:mm:ss is not considered as a valid format. And whenever input format doesn't match with the input date the tool uses the current date and time..

 

Yes.
