           Summary: [Web Inspector] Performance Timeline Panel metabug
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: Web Inspector

For W3C specs, Performance Timeline[1], Resource Timing[2] and User Timing[3] are now in CR, Navigation Timing[4] is already in PR. Those specs provide unified and easily access interface to measure kinds of timing information, including resource fetch, user self-defined timestamps etc. Base on them, we can enhance web inspector to provide visualization of these timings in a timeline panel, which can help web developer identify performance bottleneck.
