Visualising multiple time zones

A non-transitory computer readable medium, including computer-executable instructions stored thereon that when executed by a processor causes the processor to perform a method comprising:

• (a) receiving or determining first trip data that identifies a trip day, a first time zone associated with a departure location and a second time zone associated with an arrival location, the second time zone being different to the first time zone;
• (b) determining based on the first trip data time gained or time lost due to travelling from the first time zone into the second time zone;
• and
• (c) causing the display of:
• a first time range representing at least part of the trip day with time values extending to the end of the trip day, the end of the trip day being relative to the first time zone, and
• a graphical element extending from the day change and having an extension based on the difference between first and second time zones, such that the graphical element indicates the determined time gained or time lost due to travelling from the first time zone into the second time zone.

A computer system for visualising multiple time zones in a calendar, the computer system comprising:

• an input port to receive or a processor to determining first trip data that identifies a trip day, a first time zone associated with a departure location and a second time zone associated with an arrival location, the second time zone being different to the first time zone;
• a processor to determine based on the first trip data time gained or time lost due to travelling from the first time zone into the second time zone, and to cause the display of:
• a first time range representing at least part of the trip day with time values extending to the end of the trip day, the end of the trip day being relative to the first time zone, and
• a graphical element extending from the day change and having an extension based on the difference between first and second time zones, such that the graphical element indicates the determined time gained or time lost due to travelling from the first time zone into the second time zone.
