What shell are you using? That doesn't work for me using Centos 4.4. My original command was time (ls; ls). I just tried you example and that doesn't work, either. I'm using bash.

3.1.17 works (FC6); 3.00.16 doesn't (CentOS 4.4).

But the following works in every shell I tested (those before and also 2.05b, CentOS 3.8): time { echo a; echo b; } a b

real 0m0.000s user 0m0.000s sys 0m0.000s

Note that the following *has* to work everywhere, but also includes the penalty of starting a new shell: time sh -c 'echo a; echo b'
