Disable timestamps in build environment or log from outside of the container?

[ypid]

I added timestamps to logs to see how long a step took: https://github.com/hashbang/aosp-build/commit/ca759a9773f14403bbd401dd2d5d86391d2fbb1b

But this should have never worked because the time is pinned/faked and frozen. It will need to be rethought.
