+
+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](https://arxiv.org/abs/2407.03525).

+## 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.
