英文解釈

Your role on the show will be from 26 August through 17 September, during which time you will be required to be on set between the hours of 7 A.M. and 4 P.M. daily to act as an advisor to contestants on the program.

この文のwhich time..のwhichは関係代名詞だと思うのですが、
which you will..ではなく、which time you will..となるのはなぜですか？

which 名詞（time）+形容詞節の主語（you）となることに違和感があるのですが、
よく見る構造でしょうか？
