Class Timestamp

constructor

• new Timestamp(seconds, nanoseconds): Timestamp

• Creates a new timestamp.

  Parameters

  • seconds: number

    The number of seconds of UTC time since Unix epoch 1970-01-01T00:00:00Z. Must be from 0001-01-01T00:00:00Z to 9999-12-31T23:59:59Z inclusive.

  • nanoseconds: number

    The non-negative fractions of a second at nanosecond resolution. Negative second values with fractions must still have non-negative nanoseconds values that count forward in time. Must be from 0 to 999,999,999 inclusive.

  Returns Timestamp

Readonly nanoseconds

Readonly seconds

isEqual

• isEqual(other): boolean

• Returns true if this Timestamp is equal to the provided one.

  Parameters

  • other: Timestamp

    The Timestamp to compare against.

  Returns boolean

  true if this Timestamp is equal to the provided one.

toDate

• toDate(): Date

• Converts a Timestamp to a JavaScript Date object. This conversion causes a loss of precision since Date objects only support millisecond precision.

  Returns Date

  JavaScript Date object representing the same point in time as this Timestamp, with millisecond precision.

toJSON

• toJSON(): {
      nanoseconds: number;
      seconds: number;
  }

• Returns a JSON-serializable representation of this Timestamp.

  Returns {
      nanoseconds: number;
      seconds: number;
  }

  • nanoseconds: number

  • seconds: number

toMillis

• toMillis(): number

• Converts a Timestamp to a numeric timestamp (in milliseconds since epoch). This operation causes a loss of precision.

  Returns number

  The point in time corresponding to this timestamp, represented as the number of milliseconds since Unix epoch 1970-01-01T00:00:00Z.

toString

• toString(): string

• Returns a textual representation of this Timestamp.

  Returns string

valueOf

• valueOf(): string

• Converts this object to a primitive string, which allows Timestamp objects to be compared using the >, <=, >= and > operators.

  Returns string

Static fromDate

• fromDate(date): Timestamp

• Creates a new timestamp from the given date.

  Parameters

  • date: Date

    The date to initialize the Timestamp from.

  Returns Timestamp

  A new Timestamp representing the same point in time as the given date.

Static fromMillis

• fromMillis(milliseconds): Timestamp

• Creates a new timestamp from the given number of milliseconds.

  Parameters

  • milliseconds: number

    Number of milliseconds since Unix epoch 1970-01-01T00:00:00Z.

  Returns Timestamp

  A new Timestamp representing the same point in time as the given number of milliseconds.

Static now

• now(): Timestamp

• Creates a new timestamp with the current date, with millisecond precision.

  Returns Timestamp

  a new timestamp representing the current date.
