Prompt
"Generate an image representing Greenwich Mean Time (GMT) as a concept, incorporating elements that signify its role as a standard civil time, its origin at the Royal Observatory in Greenwich, London, and its significance in global timekeeping. Include a classic astronomical clock face in the foreground, with the Prime Meridian line (0°) prominently displayed in the background, alongside a subtle map or globe highlighting regions that observe GMT. The style should be informative, blending historical and modern elements, with a neutral color palette that conveys a sense of timelessness and universality."
