For the record, note also

1. -date()- is a function, not a command. Stata is strict on the
difference: commands and functions work differently and are documented
separately.

2. The effect of -date()- with Steven's syntax and Steven's data would
be a numeric variable that is all missing. String variables can be
empty; numeric variables will be missing whenever Stata can't produce
non-missing values.
