WHY DOES THE READER HAVE TO ADD AN HOUR FOR SUMMERTIME?
Lavers tide tables show all times in Universal Time, formerly called Greenwich Mean Time. This is because many marine professionals depend on the tables for their work and U.T. is the accepted standard for time at sea. Also, British Summer Time dates have been known to change at short notice so standardising on U.T. (G.M.T.) means the tables are technically correct regardless of any bureaucratic rulings.
