Given how high a selling point this is, it is something that I cannot recall ever using in ArcticDB (5+ years of using). It's (financial) time series data, the past doesn't change.
Back adjusting futures contracts or back adjusting for dividends / splits come to mind as I write this, but I would just reprocess these tasks from the raw data "as of date" if needed.
