User Timing Level 2 advances to CR

The "User Timing Level 2" specification has moved from W3C Working Draft (WD) to Candidate Recommendation (CR) status. It is a relatively small update of the existing "User Timing" specification that became a W3C Recommendation (REC) in December 2013.

Web developers need the ability to assess and understand the performance characteristics of their applications. While JavaScript provides a mechanism to measure application latency, the precision of this timestamp varies between user agents. "User Timing" defines interfaces which expose a high precision, monotonically increasing timestamp, so that developers can better measure the performance characteristics of their applications.

The abstract of the updated "User Timing Level 2" CR reads as follows:

"This specification defines an interface to help web developers measure the performance of their applications by giving them access to high precision timestamps."
