# 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.
