As discussed in #2900, the milliseconds are rarely useful, and it can be confusing with different timezones because it makes harder to compare timestamps. I added an environment variable to control the timestamp in a cross-platform way. I didn't document because it exists only for tests (like `JJ_RANDOMNESS_SEED`). Closes #2900
