GMT (Greenwich Mean Time) is not always UK time due to British Summer Time (BST). From the last Sunday in March to the last Sunday in October, the UK is on BST, which is GMT+1, aligning with Central European Time. Outside these months, UK time reverts to GMT. To determine UK time, consider whether you're within these summer months.
