When Fitz goes into Cryogenic hibernation his eyes are open. In the future when awakened his eyes are closed.
At 24:19- when Fitz and the group "time warp" only the soldiers notice the lost 1/2 hour of time OR no one notices the soldiers "frozen" in place for that 1/2 hour. However, device was said to work in a 2 mile-radius, so people nearby would also be frozen, probably with everyone entering radius during that time.
Just before Fitz awakes from inside the cryogenic pod, the countdown timer on the pod is shown as it reaches 0. The display for the countdown timer uses 6 digits for the total amount of minutes. However, 74 years equals to just under 39 million minutes, which is an eight digit number.
