Unlock a locked Workout

So I am in week three of the Gran Fondo training plan, but this week I have only started doing to the workouts today. I got up early and did the endurance ride at 5.30am and was planning to do a workout after work but the workout is locked until 10.25 pm.
Is there any way to get around this? I tired changing the date on my computer before but it didn’t seem to work.

This has been an ongoing complaint that just doesn’t ever get addressed by Zwift. I recommend getting a training plan from another source.
