翻译：The time between the turn of the century 1900..

The time between the turn of the century 1900-1955 is less than the amount of time between when DiSneyland opened and today by 7 years.
请问这句话如何翻译，与最后的by 7 years 是什么成分？

The time between the turn of the century 1900-1955 is less than the amount of time between when DiSneyland opened and today by 7 years.

1900年-1955年这期间比迪斯尼乐园开园到今天的时间短七年。（即迪斯尼乐园的历史已经有62年了。）by 7 years是is less的程度状语，表示实质多或少的量。
