I see the same behavior, I don't like it and I don't think it provides good User Experience, but since the time synchronizes across the model, then when you open a dashboard ( or a module) it'll synchronize accordingly until you actively change it.
I would agree with both you and @Misbah . But have you considered an alternative solution:
By using a input module and having the user make a selection within a Line Item, preferably dimensionalised by user. You could drive a filter module linked to the view. So your table would be time synchronised with the selection, but not with other tables.
