It's been official for some time.  But broken for Windows/SWF.  And  
you needed a Wizard to operate it.  Less so now, but you probably  
still need a Wizard to make any sense of what it tells you... :)

It is still the case that for Windows (and for DHTML, at least under  
Mozilla) the clock resolution is poor, so the measurements are  
sloppy.  On Mac SWF, (new Date).getTime() returns a cock accurate to  
10us (i.e., it gives you ms as a float with 2 digits of precision).   
Everybody else only returns ms.  Sad given that in JS all numbers are  
floats and surely the underlying hardware clock is more accurate than  
ms...
