# getBlockTime - Solana

This method returns the estimated production time of a block as a Unix timestamp. The estimate is derived from stake-weighted validator timestamp oracles.

| --------- | ------ | -------- | --------------------------------- |
| slot      | number | Yes      | Slot number of the block to query |

## Response Parameters

| Parameter | Type   | Description                             |
| --------- | ------ | --------------------------------------- |
