BlockTimestamp

Creates a block timestamp object

Rarely used, typically in blockchain block headers

Constructors

• constructor(
    public slot: u32 = 0
  )
  

  slot - Blocks since epoch

_Example:

  import { BlockTimestamp } from 'proton-tsc'

  const bt = new BlockTimestamp(5)
  // tp.slot == 5

• static fromTimePoint(t: TimePoint): BlockTimestamp
  

  Creates a BlockTimestamp object from a precise TimePoint

• static fromTimePointSec(t: TimePointSec): BlockTimestamp
  

  Creates a BlockTimestamp object from a precise TimePointSec

Static Fields

• static blockIntervalMs: i32 = 500;
  

  Represents interval between each block

• static blockTimestampEpoch: i64 = 946684800000;
  

  Start of epoch

Static Methods

• static function maximum(): BlockTimestamp
  

  Returns block timestamp of 0xffff (65535)

• static function min(): BlockTimestamp
  

  Returns block timestamp of 0

Instance Methods

• function next(): BlockTimestamp
  

  Returns a new BlockTimestamp with slot incremented by 1

• function toTimePoint(): TimePoint
  

  Convert block timestamp to a TimePoint object

• function setTimePoint(t: TimePoint): void
  

  Sets the slot field using a time point

• function setTimePointSec(t: TimePointSec): void
  

  Sets the slot field using a time point sec

• function toString(): string
  

  Returns string representation of number of slots since epoch

Static Equality methods

• static function eq(a: BlockTimestamp, b: BlockTimestamp): bool
  

  Checks that the slots of the two block timestamps are equal

• static function neq(a: BlockTimestamp, b: BlockTimestamp): bool
  

  Checks that the slots of the two block timestamps are not equal

• static function lt(a: BlockTimestamp, b: BlockTimestamp): bool
  

  Checks that the slot of a is less than b

• static function lte(a: BlockTimestamp, b: BlockTimestamp): bool
  

  Checks that the slot of a is less than or equal to b

• static function gt(a: BlockTimestamp, b: BlockTimestamp): bool
  

  Checks that the slot of a is greater than b

• static function gte(a: BlockTimestamp, b: BlockTimestamp): bool
  

  Checks that the slot of a is greater than or equal to b
