Titanic's clock

[Mila]

I've read that Boxhall testified that the measurements that were used to calculate their position were taken at 7:30. He also said three stars were used to do the measurements, but no stars should have been visible at 7:30 because it still was daylight. The sunset was somewhere after 9.

What I am missing?

Thanks.

You are missing commonsense. At a glance, sunset at 9pm in April at around 42°N is wrong, as anybody who lives in that latitude could tell you. That's more like midsummer in a very high latitude. Without working it out exactly, my trusty Norton's tells me that sunset was a few minutes after 6-30pm, which is near enough, as we don't know for sure how Titanic's clocks were set. (Let's not get into that argument).
