Past tense or present tense

I heard following sentence from one of videos I've watched. Though, it is clear that they talk about a past event, why they have use "is" to talk about the time period in that introduced the farming economy. If I had written this sentence, I would have use "is when a total farming economy was introduces" instead of the following sentence. Therefore, I would really appreciate it, if someone could explain this and why they have used present tense instead of past tense in the following sentence


Today, we're going to move on to period between four and six thousand year ago, known as the Neolithic period, which is when a total farming economy was introduced in Ireland.
