The latest version of High Resolution Time is ready for wide review.

One can find the latest draft at:

High Resolution Time Level 2 replaces the first version of High 
Resolution Time [HR-TIME] and includes:

* Defines a precise definition of time origin for the purpose of all 
performance timeline related specifications;

* Provides the base definition for the Performance interface, including 
support for the Performance.now method in Web Workers [WORKERS];

* Introduces the method Performance.translateTime to compare times 
between different time origins;

* To mitigate cache attacks, the recommended minimum resolution of the 
Performance interface should be set to 5 microseconds.

The method Performance.translateTime is marked as "at risk" to the 
purpose of moving High Resolution Time 2 to W3C Recommendation due to 
its lack of implementation experience. It is expected to be deferred 
until the next release at the moment.

New issues are welcome at
