Struct nakamoto_common::block::time::AdjustedTime

pub struct AdjustedTime<K> { /* private fields */ }

Network-adjusted time tracker.

Network-adjusted time is the median timestamp of all connected peers. Since we store only time offsets for each peer, the network-adjusted time is the local time plus the median offset of all connected peers.

Nb. Network time is never adjusted more than 70 minutes from local system time.

Implementations

impl<K: Hash + Eq> AdjustedTime<K>

pub fn new(local_time: LocalTime) -> Self

Create a new network-adjusted time tracker. Starts with a single sample of zero.

pub fn record_offset(&mut self, source: K, sample: TimeOffset)

Add a time sample to influence the network-adjusted time.

pub fn offset(&self) -> TimeOffset

Get the median network time offset.

pub fn from(&self, time: BlockTime) -> BlockTime

Get the network-adjusted time given a local time.

pub fn get(&self) -> BlockTime

Get the current network-adjusted time.

pub fn set_local_time(&mut self, time: LocalTime)

Set the local time to the given value.

pub fn local_time(&self) -> LocalTime

Get the last known local time.

Trait Implementations

impl<K: Eq + Clone + Hash> AdjustedClock<K> for AdjustedTime<K>

fn record_offset(&mut self, source: K, sample: TimeOffset)

Record a peer offset.

fn set(&mut self, local_time: LocalTime)

Set the local time.

impl<K: Eq + Clone + Hash> Clock for AdjustedTime<K>

fn block_time(&self) -> BlockTime

Return the local time as seconds since Epoch. This is the same representation as used in block header timestamps.

fn local_time(&self) -> LocalTime

Tell the time in local time.

fn from_block_time(t: BlockTime) -> Self

Create a clock from a block time.

impl<K: Clone> Clone for AdjustedTime<K>

fn clone(&self) -> AdjustedTime<K>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<K: Debug> Debug for AdjustedTime<K>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<K: Hash + Eq> Default for AdjustedTime<K>

fn default() -> Self

Returns the “default value” for a type.
