Thanks for the hint. Fortunately, I just needed the date in the format 
[year,/,mm,/,dd], so I can do something like

\expanded{\setvariables[test:date][\getvariable{test}{date}]}

\immediate\openout \scratchwrite test-001
\immediate\write   \scratchwrite {The date entered was}
\immediate\write   \scratchwrite 
{\getvariable{test:date}{y}/\getvariable{test:date}{m}/\getvariable{test:date}{d}}

\closeout\scratchwrite
