time is not a builtin. It's a "keyword". It's a piece of the shell's
syntax. It has special magical rules that apply to nothing else.
If you want to set an environment variable in the temporary execution
environment of a command, and time how long that command takes, then
you write it like this:
time TEST=1 something that is not actually ls because ls does not use \$TEST

Completely useless. cd does not use environment variables.
