Ok. That's fine. :) But then why call them "time sights"? They're just "sights". And indeed, that's really the big lesson of modern "intercept" navigation methods: any and all sights are "just sights". There's no need for Polaris sights, no need for Noon Sun, no need for ex-meridian sights, and no time sights. You just shoot any altitude and compare with the simulated altitude from some nearby known point: difference is distance, away or towards on the simulated azimuth. Plot your LOP and move on the next body. And that's that.

If you DO still want to experiment with historical methodology, then you should try some time sights when the Sun is within roughly 45 degrees of east or west.
