Your blueprint, computed.

Why is this off by default? In our tracked results, uncorrected clock time reads more accurately than solar-corrected time for most people. We don't fully know why — the working hypothesis is that timing structure follows the time system you live by and identify with, not your geographic longitude. We are empiricists: we ship whichever convention verifies better, and we say so when we can't explain it. Turn this on only if you have a specific reason to.
