The new Uize.now static method, implemented in the Uize base module, returns the current time in milliseconds since 1970 (POSIX time).

SYNTAX

nowMsINT = Uize.now ();

The Uize.now method is optimized to use the Date.now static method that is supported by JavaScript's built-in Date object in newer versions of the language. If this method is not available, then the Uize.now method falls back to using the less performant +new Date approach, which involves construction of a Date object instance each time.

The Uize.now method can be useful when capturing start and end times in order to measure the duration of operations. Consider the following example...

EXAMPLE

var start = Uize.now ();

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

var duration = Uize.now () - start;

Using the above template, the value of the duration variable will indicate how long it took to perform the operations in the block between assigning the value for the start variable and the value for the duration variable.
