I think you can subtract dates in Teradata to get # days difference.  If the data are timestamps, you might need to cast as date before subtracting.

Probably better off asking in a teradata forum?

All database or quasi-database (ie Excel) systems store dates as numbers. Dates are typically stored as # of days from a given offset (1 Jan 1960 in SAS, 31 Dec 1899 in LibreOffice Calc/Excel), timestamps as # of seconds from the same offset.

So if you have real date values, simple subtracting will work, if you have timestamps, int(value1/86400) - int(value2/86400) will do the trick.
