Final answer:
Yes, it's usually okay to use a general time reference if the exact date of an event is not known or remembered. However, accuracy can decrease over time, even in the case of significant events, as demonstrated by inaccuracies in flashbulb memories.
Step-by-step explanation:
True, it is generally acceptable to use a general time reference if you do not recall the exact date of an event. For example, historical narratives often say things like 'in the late 1800s' or 'in the early 20th century' when the specific date is not known or is not necessary for the understanding of the story being told. However, this concept does not apply to all situations, especially when it comes to memory and recollection.
Flashbulb memories, such as a person's memory of the events of 9/11, can become less accurate over time. Even important people like President George W. Bush have been known to recount the events and times of such instances inaccurately as time passes. These inaccuracies showcase that our memories are not always reliable sources of factual historical information, but general time references can help recall the less accurate details.
