Hello Steven.Off topic comment be me:...I hear you. I'm so ready for Winter to be over. The cold sucks. One of the reasons why I sympathize with the people on Titanic. But back to the subject matter. After looking at the times I can see why they are listed as they are. There's no way one could be exact about it and a minute here or there doesn't change the story at all IMO. It's not like today with people taking selfies where you can extract the metadata and get the time down to the second.
I completely agree with your remarks regarding the inexactitude of assessing times. However, I am not concerned with that but of glaring anomalies in The Table 2 under discussion. Look closely and make your own mind up. here is what I see:
As you can see from the above, I have inserted the evidence of QM Rowe concerning his times of firing the signals.
Rowe also said he first contacted the bridge to tell them about boat 7 at 12-25 am by his watch which was at least 23 minutes SLOW of unaltered time .This means the bridge time would have been 12-48 am. which agrees with The Table.
However, since Rowe said he commenced firing signals at about 12-45 am,.20 minutes later, The Table should record a time of 1-08 am instead of 12-47 am as is does.
It seems that the difference between The Table time and the partly altered time for the launching of the first signal has been reduced to almost zero. Otherwise why is The Table time of firing the first signal a mere 2 minutes adrift from the time given by QM Rowe whose watch was 23 minutes SLOW of ship time?
As a further puzzle, The Table times suggest that boat 5 was launched at 12-40 am and boat 7 five minutes after that, at 12-45 am which was 12-17am and 12-22am respectively on Rowe's watch and 3 minutes before 12-25am when he reported to the bridge that he had seen one boat in the water.
To compound the felony, The Table shows the first rocket being fired at 12-47 am which was 12-24 am on Rowe's watch -a minute before he called the bridge.
So the simplified picture painted in terms of a partially retarded clock is as follows:
12-17 am...boat 7 seen. - 12-40 am Table
12-22 am...boat 5 seen. - 12-45 am Table
12-24 am... first signal fired. - 12-47 am Table
12-25 am... Rowe advises bridge of seeing boat 7 - 12-48am Table
However, if we move on in the table, we find everything returns to normal re time differences.
As they use to ask in the TV show "Soap",,, "Confused? You will be after this next episode."
