Please review the spec and provide feedback. "The DOMHighResTimeStamp is a double-precision floating-point number and is bound to the double type of ECMAScript." -- the second part doesn't make sense. There is no "double" type in ECMAScript. Did you mean Number? I don't actually see a need for this entire paragraph, since it's all covered in IDL already. In fact, I'd prefer not having prose that duplicates the IDL... Are there security concerns about subframes being able to extract "now" information relative to the navigation start of the root document? "The difference between any two chronologically recorded time values of the now attribute MUST never be negative or zero." -- I'm not sure what the "MUST never be zero" requirement means in practice. If the return value is only accurate to 0.1ms, then it seems quite possible to get it twice in a row and end up with the same value on modern hardware, but the text seems to prohibit that behavior. Am I missing something? The rest of this looks just fine. Thank you for putting it together! -Boris
