In this case you are loosing a day, or in other words, adding 24 hours to your watch.
Did you know that one country, Kiribati, that lies around the international Dateline used to have the problem that the two parts of the country had similar time, but different days? The offices could only communicate on 3 days of the week, as during the rest of the time at least one part of the country had a weeked. This was changed in 1995 and now the whole of Kiribati lies on the west side of the line and also has the most advanced time on earth.
Thee forms of nationalism, from the list:

Geography can play a role in the formation of nations. But when we speak of types of nationalism, we generally refer to ideas around which a nationalist feeling is based.
Ethnic nationalism focuses on shared ethnic identity, seen in common language, racial group, etc.
Political nationalism focuses on loyalty to the political state in which one resides--to its ideology and political system. In its formation, the United States served as an example of this form of nationalism, uniting around a shared idea.
Cultural nationalism (not listed above) sits between ethnic and political nationalism, incorporating features of both. It focuses on shared traditions within a country. Though it may have some connection to ethnic commonality, the greater emphasis is on shared experience and national traditions.
Religious nationalism sees a connection between a particular religious identity and national identity. A Muslim nation that operates under Sharia law would be an example. The United States can also be an example if/when people describe the US as "a Christian nation" and see patriotism aligning with principles of the Christian religion.
