I just purchased the SCJD Assignment 2 days ago and received this in my email:

You have one year to complete the SCJD assignment.
So I checked on these sites (Canada and US):
And found they both say:
Time limit: 12 months from assignment download
Has something changed or have I misread something... In the event something has changed, perhaps the FAQ should change as well.
