# Time comparisons

Back to: [Index of transforms](../cards-transform-table-index/index.md)

Transforms in this section compare a [time data type](../analysis-data-model/index.md).
These comparison transforms are useful for filtering transform table rows by time columns. These comparison transforms can also be used separately outside of transform tables.
