Of course it is time. Anything, a thought, an action, an event that has a beginning a middle and an end has duration. ...
The Lord himself said that he created over a number of days, resting on the seventh. The creator describes his own actions in a 3D time & space realm.
btw; No response received from christians regarding what dimensional form Jesus takes in heaven.
If a physical presence, then it makes heaven seem like a rather ordinary place, if ethereal , then someone needs to explain where the physical organic body of Jesus ended up.
maybe its been put into a cryo state waiting to be kick started for JCs return.
some folks have dared to suggest that jesus when he ascended turned into pure light - love?
the story about his ascending in bodily form was yet another roman effort to make sense, or deny the real event.
