UnSeenTimeQA: Time-Sensitive Question-Answering Beyond LLMs’ Memorization [ACL 2025]


We introduce UnSeenTimeQA, a novel data contamination-free time-sensitive question-answering (TSQA) benchmark. It differs from existing TSQA benchmarks by avoiding web-searchable queries grounded in the real world. We present a series of time-sensitive event scenarios based on synthetically generated facts. It requires large language models (LLMs) to engage in genuine temporal reasoning without depending on the factual knowledge acquired during the pre-training phase. We designed three types of time-sensitive questions to test LLMs' temporal reasoning abilities over sequential and parallel event occurrences. Please refer to our paper here.

Dataset

Different types of events (six) from the UnSeenTimeQA benchmark. The benchmark is structured into four difficulty levels: easy, medium, hard (serial), and hard (parallel).

In the easy level, the start (S) and end (E) times of each event are given.

The medium level includes the start time (S) and duration (D) of each event.

The hard (serial) level presents only the duration (D) of events, assuming sequential occurrence.

The hard (parallel) level also includes only durations (D), but events can occur simultaneously.
