What tag should be used for the Cumulative effect of the change in accounting principle on the equity statement? This is related to the recent adoption of Revenue Recognition principle. The tag that I'm looking for is should have a duration type. I have found this one us-gaap:CumulativeEffectOfNewAccountingPrincipleInPeriodOfAdoption, but it has an instant type, while I need a duration type. I'll have to create a custom tag, if no one suggests a better standard tag.
