I noticed something strange.
The default expression in creation date column contains the NOW () expression.
If you import the CSV in that state, the time 9 hours ago will be automatically entered in the column.
My current timezone is Tokyo, so I think it was automatically entered in UTC time.
Is there a way to automatically enter the local time?
This should not be a bug, but it tells how AppSheet import action is gonna work.
When we set the initial value to NOW(), then the expression is always evaluated at server side, event though import action is initiated from client side.
If you are sure your app is always used in Japan, please try the following expression as initial value.
