Edexcel Biology exam lengths for AS/A2?

As the title says? how much time do you have to fill in the exam paper?

According to the Specification:
http://www.edexcel.com/migrationdocuments/GCE%20New%20GCE/UA024831%20GCE%20in%20Biology%20Issue%204%20250510.pdf

AS: 1 Hour 15 minutes
A2: 1 Hour 30 minutes

However if you look at their specimen papers
http://www.edexcel.com/migrationdocuments/QP%20GCE%20Curriculum%202000/January%202011%20-%20QP/6BI01_01_que_20110111.pdf

AS: 1 Hour 30 minutes
A2: 1 Hour 45 minutes.

Which is 15 minutes longer for each.

Does anyone know what is the actual length?
