Review comment:
I don't think it makes much sense to have an increment time column:
1. Main time column cannot be changed because it is used to manage the
upsert events
2. Time column should follow the configured time format
3. I don't see a use case where user would put the delta value for time
instead of the actual value. It is hard to manage a flow to have the initial
value as the first event
