the process.hrtime()
is a legacy version of process.hrtime.bigint()
method
process.hrtime(); // -> [27511, 516453000] (seconds, remaining nanoseconds)
process.hrtime.bigint(); // -> 27511516453000n (nanoseconds)
27511516453000 nanoseconds are 7.6420879036111113 hours
When I'm Testing this the time is 11:54 UTC and 14:54 Locale Time
process. cwd() returns the current working directory, i.e. the directory from which you invoked the node command. __dirname returns the directory name of the directory containing the JavaScript source code file.
The process object in Node. js is a global object that can be accessed inside any module without requiring it. There are very few global objects or properties provided in Node. js and process is one of them. It is an essential component in the Node.
The process. argv() method is used for returning all the command-line arguments that were passed when the Node. js process was being launched. The first element will always contains the same value as process.
The process. exit() method is used to end the process which is running at the same time with an exit code in NodeJS. Syntax: process.exit( code ) Parameter: This function accepts single parameter as mentioned above and described below: Code: It can be either 0 or 1.
The Advantage of process.hrtime () is it measures time very accurate execution time which last less than a millisecond. Parameter: This method accept a single parameter as mentioned above an described below. time : The time is an optional paramete r that must be the result of a previous process.hrtime () call to difference with the current time.
As for the actual hrtime.bigint () issue, you might have to either add/update your @types/node type declarations dependency and/or Node itself... In my own project, I've also used this code below for providing backward compatibility with older Node versions (though w/ obvious lack of precision):
Node.js process.hrtime ( ) Method. The process.hrtime () method to measure code execution time which returns array which include current high-resolution real time in a [seconds, nanoseconds]. We measure the code execution time by providing the time returned by the first process.hrtime () call as a parameter in the second process.hrtime () call.
time : The time is an optional paramete r that must be the result of a previous process.hrtime () call to difference with the current time. Return Type: It returns an array of 2 ints. The 1. int contains the seconds and the 2. int the nanoseconds. These times are relative to an arbitrary time in the past, and not related to the time of day.
The meaning of these values is defined in the documentation (although it's easy to miss, since it's just one line):
These times are relative to an arbitrary time in the past, and not related to the time of day and therefore not subject to clock drift.
So in other words, hrtime
is only useful for calculating the time relative to another point in time. If you call hrtime
now, and then again ten seconds in the future, the result of subtracting the former from the latter will equal ten seconds. The values returned by those two calls, however, have no real meaning in isolation from each other.
