Display correct itinerary items when a ship crosses the IDL

International date line crossing

Display correct itinerary items when a ship crosses the IDL. The IDL crossing needs to be configured with one of the following options:, _(*1)

• NO - normal item
• EASTBOUND - item represents IDL crossing Eastbound, gaining a day. The item however is just a marker, it does not take any time (e.g. Day3: IDL crossing, Day3: watching sea-turtles mate).
• EASTBOUND_DAY - item represents IDL crossing Eastbound, gaining a day. The item represents a day of activity and will count as a day as well (e.g. Day3: Crossing IDL and watching sea-turtles mate).
• WESTBOUND - item represents IDL crossing Westbound, loosing a day. The item however is just a marker, it does not take any time (e.g. Day3: IDL crossing, Day3: watching sea-turtles mate).
• WESTBOUND_DAY - item represents IDL crossing Westbound, loosing a day. The item represents a day of activity and will count as a day as well (e.g. Day3: Crossing IDL and watching sea-turtles mate).

Example crossings are:, _(*2)

1) Ship sails from Asia to US across the pacific ocean (going EASTBOUND) - you gain a day as you are loosing hours all the time, _(*3)

2) Same, but the crossing represents a whole day, _(*4)

3) Ship sails from US to Asia across the pacific ocean (going EASTBOUND) - you loose a day as you are gaining hours all the time, _(*5)

4) Same, but the crossing represents a whole day, _(*6)

Usage

Please see the tests for examples. Basically you define a list of itinerary items and set the IDL options on some of them. Days and dates will then be adjusted accordingly., _(*7)
