@stdlib/time-duration2ms

About stdlib...

We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js.

The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases.

When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there.

To join us in bringing numerical computing to the web, get started by checking us out on GitHub, and please consider financially supporting stdlib. We greatly appreciate your continued support!

duration2ms

Convert a duration string to milliseconds.

Installation

npm install @stdlib/time-duration2ms

Usage

var duration2ms = require( '@stdlib/time-duration2ms' );

duration2ms( str )

Converts a duration string to milliseconds.

var ms = duration2ms( '1d' );
// returns 86400000

ms = duration2ms( '1d2h3m4s5ms' );
// returns 93784005

Notes

• A duration string is a string containing a sequence of time units. A time unit is a nonnegative integer followed by a unit identifier. The following unit identifiers are supported:

  • d: days
  • h: hours
  • m: minutes
  • s: seconds
  • ms: milliseconds

  For example, the string 1m3s10ms is a duration string containing three time units: 1m (1 minute), 3s (3 seconds), and 10ms (10 milliseconds). The string 60m is a duration string containing a single time unit: 60m (60 minutes).

• Duration strings are case insensitive. For example, the string 1M3S10MS is equivalent to 1m3s10ms.

Examples

var duration2ms = require( '@stdlib/time-duration2ms' );

var ms = duration2ms( '5s20ms' );
// returns 5020

ms = duration2ms( '1h' );
// returns 3600000

ms = duration2ms( '1m2s3ms' );
// returns 62003
