GHSA-h4f5-h82v-5w4r: SurrealDB has an Uncaught Exception in Function Generating Random Time

The rand::time() function in SurrealQL generates a random time from an optional range of two Unix timestamps. Due to the underlying use of timestamp_opt from the chrono crate, this function could potentially return None in some instances, leading to a panic when unwrap was called on its result in order to return a SurrealQL datetime type to the caller of the function.
