Hi,

I am currently browsing the flow documentation and came across the page regarding block info over here: [Environment Information | Cadence](https://docs.onflow.org/cadence/language/environment-information/#block-information)

In the comment for Block timestamp it says:

> It is the local clock time of the block proposer when it generates the block

What format is it in, unix timestamp? Is there any way to map them to a non local version that is consistent across blocks?

Thank you!

It is a Unix timestamp, however, the comment is incomplete (I will update it), see: [Flow Access API Specification | Flow Developer Portal](https://docs.onflow.org/access-api#block)

> Timestamp of when the proposer claims it constructed the block.  
> **NOTE** : It is included by the proposer, there are no guarantees on how much the time stamp can deviate from the true time the block was published.  
> Consider observing blocks’ status changes yourself to get a more reliable value.
