Hi there!
Who knows, how does this book called?
Thanks.
Hi, can you explain in depth as to why we add (if required) DST later.What happens if we add DST straight away ? Thanks.
The table of values in the almanac are in the standard time zone for the port. If you make the change to DST and then use the table you are using a table in one time zone and a time from another. In some locations this might be a minor difference however in others (where there are big differences between the adjusted values) this error could be significant.
@@pzsc Hi thanks for getting back to me.
So if the Q was in DST ( Q,,What is the tidal stream for the hour of 15.00 DST till 16.00 DST ), would you convert back to UT to agree with the Almanac, then back to DST again at the end of your workings out ?.
I'm very interested in the workings out of these problems and appreciate there is usual more than one way. I hope to do YM next year so i'm a bit keen, many thanks.
@@graemebaxter9455 hi - Yes, convention should be completed in UT (or the standard time for the convention table).
Amazing knowledge! Thank you so much.
