The time difference between London and Zurich is primarily due to the variation in their geographical locations and the time zones they fall under. The concept of time zones was established to standardize time measurement across different regions around the world.

London is located in the United Kingdom, which follows Greenwich Mean Time (GMT) or British Summer Time (BST), depending on the season. GMT is the time at the Prime Meridian (0 degrees longitude) in Greenwich, London, and is considered the baseline for measuring time worldwide.

Zurich, on the other hand, is located in Switzerland, which follows Central European Time (CET) or Central European Summer Time (CEST) during daylight saving time. CET is one hour ahead of GMT.

Given that London follows GMT/BST, which is one hour behind Zurich's CET/CEST, the time in London appears to be one hour behind Zurich.

The time difference allows for coordination and synchronization of activities across different regions, ensuring that people in various locations can have standardized time references for communication, transportation, and other purposes.
