getBlockTime RPC Method
Returns the estimated production time of a block.
Info
Each validator reports their UTC time to the ledger on a regular interval by intermittently adding a timestamp to a Vote for a particular block. A requested block's time is calculated from the stake-weighted mean of the Vote timestamps in a set of recent blocks recorded on the ledger.
