Building upgrade virtual time v/ real time

[Gamla]

With respect,
if a building level upgrade sequel cost 10 days 0h ... virtual time + in real time a player is daily 02 hours online = what will it take in real time calculated to finish the upgrade ?
In hope to find a correct reply.

it takes 10 days
as long as you login everyday, the upgrade will continue when you are logged out.

As Kit says, there is no calculation.

Everything on your island continues to work, all production, all upgrades, troop training, everything continues 24/7 provided you log on once every day.

As far as I understand then 24h after your last log in the island will go to sleep.
