明日、林さんに (1 or 2) ときに、この本を返そう。 1 - 会う 2 - 会った

I chose 1 in the above statement but it was incorrect, the correct answer is 2
- 会った . I thought 会った means the PAST, so he is saying Tomorrow I will meet him
and return his book, why is he using the past form when he will meet him
tomorrow, it makes no sense at all??
