[Terminator] How was the T1000 able to time travel in T2?

If time travel only works on alive flesh, how can the all-metal T1000 travel back in time in T2? The same question applies to the terminatrix in T3.

More specifically, time travel doesn't work on metal. The T800 (Arnie) describes the T1000 as "emimetic poly-alloy" or something like that, and then uses "liquid metal" as shorthand for it. So it's not that time travel only works with flesh, just that it doesn't work with "typical" metal. The T1000 is, to put it mildly, not typical.
