it's actually 6 days.
well, i would agree but the construction is built in two days, together with the building’s face everything took six days, right?(the first clock shows the time of the base construction and the second one the time that was spent for the rest... maybe i’m wrong...)
well the newspapers report that it was 6 days. if you watch the video there are more than 2 days/nights. i guess i'm including everything in the description of construction. either way it's still amazing!
ok, come on – let’s say six days! fast enough! ;)
