Reasoning about time is essential for Large Language Models (LLMs) to understand the world. Previous works focus on solving specific tasks, primarily time-sensitive question answering. While these methods have proven effective, they cannot generalize a wider spectrum of temporal reasoning tasks. Therefore, we propose crucial question: Can build universal framework handle variety tasks? To that end, systematically study 38 Based observation 19 tasks are directly related mathematics, first...
