2.1.15 [ECMA-262/5] Section, TimeClip (time)


The specification states:

 The operator TimeClip calculates a number of milliseconds from its argument, which must be an ECMAScript Number value. This operator functions as follows: 
 1.  If time is not finite, return NaN. 
 2.  If abs(time) > 8.64 x 1015, return NaN. 
 3.  Return an implementation-dependent choice of either ToInteger(time) or ToInteger(time) + (+0). (Adding a positive zero converts −0 to +0.) 

IE9 Mode, IE10 Mode, IE11 Mode, and EdgeHTML Mode (All Versions)

In step 3, ToInteger(time) is returned.
