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.

Stop OBFUSCATING your questions.
