Timestamp in Block clarification


I am currently browsing the flow documentation and came across the page regarding block info over here: 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 Documentation

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.
