The new Uize.since static method, implemented in the Uize base module, returns the amount of time (in milliseconds) that has elapsed since the specified date.

SYNTAX

elapsedMsINT = Uize.since (dateOBJorINT);

The value provided for the dateOBJorINT parameter can be either a reference to an instance of JavaScript's built-in Date object, or an integer representing milliseconds since 1970 (POSIX time). The Uize.since method provides a semantically elegant way of dealing with the timing of processes in JavaScript and is provided merely as syntactic sugar.

INSTEAD OF...

var start = Uize.now ();

// ... ... ... ... ... ... ... ... ... ... ...
// do some stuff that may take a bunch of time
// ... ... ... ... ... ... ... ... ... ... ...

var duration = Uize.now () - start;

USE...

var start = Uize.now ();

// ... ... ... ... ... ... ... ... ... ... ...
// do some stuff that may take a bunch of time
// ... ... ... ... ... ... ... ... ... ... ...

var duration = Uize.since (start);
