The Dark Side of Open Source
At Node Congress, Socket CEO Feross Aboukhadijeh uncovers the darker aspects of open source, where applications that rely heavily on third-party dependencies can be exploited in supply chain attacks.
@google-cloud/precise-date
Advanced tools
Readme
A simple utility for precise-dateing functions and classes.
It's unlikely you will need to install this package directly, as it will be
installed as a dependency when you install other @google-cloud
packages.
$ npm install --save @google-cloud/precise-date
PreciseDate
extends the native Date
object, so you can use it in place of
that or when you need nanosecond precision.
const {PreciseDate} = require('@google-cloud/precise-date');
const date = new PreciseDate('1547253035381101032');
date.toISOString();
// => 2019-01-12T00:30:35.381101032Z
date.toFullTimeString();
// => '1547253035381101032'
Returns a new date
instance.
Type: string
BigInt
Object<string, number>
[number, number]
// from a full ISO string
date = new PreciseDate('2019-02-08T10:34:29.481145231Z');
// from a string representing nanoseconds
date = new PreciseDate('1549622069481320032');
// from a BigInt representing nanoseconds (requires Node >= 10.7)
date = new PreciseDate(1549622069481320032n);
// from an object containing `seconds` and `nanos` values
date = new PreciseDate({seconds: 1549622069, nanos: 481320032});
// from a tuple representing [seconds, nanos]
date = new PreciseDate([1549622069, 481320032]);
Similar to Date.parse()
, but this accepts the same nanosecond time options as the PreciseDate
constructor and returns a string representing the nanoseconds in the specified date according to universal time.
PreciseDate.parseFull('2019-02-08T10:34:29.481145231Z');
// => '1549622069481145231'
Similar to Date.UTC()
, but also accepts microsecond and nanosecond parameters. Returns a string that represents the number of nanoseconds since January 1, 1970, 00:00:00 UTC.
Type: ...number
PreciseDate.fullUTCString(2019, 1, 8, 10, 34, 29, 481, 145, 231);
// => '1549622069481145231'
Like PreciseDate.fullUTCString()
but returns a native BigInt
instead of a string. Requires Node >= 10.7.
Type: ...number
PreciseDate.fullUTC(2019, 1, 8, 10, 34, 29, 481, 145, 231);
// => 1549622069481145231n
PreciseDate
instance.
Returns a string of the specified date represented in nanoseconds according to universal time.
Like date.getFullTimeString()
but returns a native BigInt
instead of a string. Requires Node >= 10.7.
Returns the microseconds in the specified date according to universal time.
Returns the nanoseconds in the specified date according to universal time.
Sets the microseconds for a specified date according to universal time. Returns a string representing the nanoseconds in the specified date according to universal time.
Type: number
Sets the nanoseconds for a specified date according to universal time. Returns a string representing the nanoseconds in the specified date according to universal time.
Type: number
Sets the time to the number of supplied nanoseconds since January 1, 1970, 00:00:00 UTC. Returns a string representing the nanoseconds in the specified date according to universal time (effectively, the value of the argument).
Type: number
string
BigInt
Returns an object representing the specified date according to universal time.
Refer to google.protobuf.Timestamp
for more information about this format.
const {seconds, nanos} = date.toStruct();
Like date.toStruct()
but returns the seconds
and nanos
as a tuple.
const [seconds, nanos] = date.toTuple();
