# identity/TimeInterval #level100 #cur #finops #curfield This field gives the interval this line applies to. It can be minutes, hours, days or even month. ## Source - Category: [[Identity details]] - [AWS Documentation](https://docs.aws.amazon.com/cur/latest/userguide/identity-columns.html) ## Relevant Notes - This field plus [[identity_LineItemId]] may to provide a [[Primary keys for the CUR]] ## Notes - Provide start and end of the row. This information is then replicated into two fields [[lineItem_UsageEndDate]] and [[lineItem_UsageStartDate]] - TimeInterval is what makes me think that inside AWS the CUR files are managed as a [[Fact table]] as in the current format they are not of great use.
