The key is that `time' is not a builtin command; it's a reserved word that
modifies an attribute of a command or pipeline. The timing information
is printed by the shell after it executes the command or pipeline to
be timed. So you need to run a timed command in a context where you
can capture the output of that context, like a subshell or group command.
