In awk, systemreturns the exit status of the command and not its standard output (unlike command substitution a.k.a. backticks). So, in your case, date will write to standard output wherever that is going.

You could use a pipe instead:
Code:
awk 'BEGIN{"date"|getline d; print "Current date is:" , d }'
