TimeUnit js
TimeUnit is a port of Doug Lea's public domain TimeUnit Java class
to JavaScript. It was ported from the
backport-util-concurrent version.
This class is the basis for java.util.concurrent.TimeUnit
from JavaSE.
Ported by Jason Walton, released under the public domain.
About
A timeunit
represents time durations at a given unit of
granularity and provides utility methods to convert across units,
and to perform delay operations in these units. A
timeunit
does not maintain time information, but only
helps organize and use time representations that may be maintained
separately across various contexts.
A timeunit
is mainly used to inform time-based methods
how a given timing parameter should be interpreted. Time units may be passed as constants
to other methods:
wait(50, timeunit.seconds);
Or can be used to perform conversions, such as converting 5 seconds into 5000 milliseconds:
timeunit.seconds.toMilliseconds(5); // Returns 5000
timeunit.milliseconds.convert(5, timeunit.seconds); // Returns 5000
timeunit
also define the very handy sleep()
function, which schedules a function for future
execution using setTimeout()
:
timeunit.seconds.sleep(5, function() {
console.log("Hello after 5 seconds!");
});
Perhaps even more useful in CoffeeScript, where it is a little easier to use that setTimeout, since it follows the "callback at the end" idiom used by most node.js code:
timeunit.seconds.sleep 5, () ->
console.log "Hello world"
As opposed to the somewhat less pretty:
setTimeout (()->
console.log "Hello world"
), 5000
A nanosecond is defined as one thousandth of a microsecond, a microsecond as one thousandth of a millisecond, a millisecond as one thousandth of a second, a minute as sixty seconds, an hour as sixty minutes, and a day as twenty four hours.
Compatibilty
timeunit
uses UMD for it's module definition, so should work in
node.js, in the browser (via the timeunit
global), via
AMD/Require.js and via browersify.
node.js
Install in node.js with:
npm install timeunit
bower
Install with:
bower install timeunit
