           Summary: JSC command-line tool does not come with any facility
                    for measuring time precisely
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: All
        OS/Version: All
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: fpizlo at apple.com


The only facility for measuring time is Date, which clips and truncates the time.  Internally, JSC has access to the most precise available method on any given OS.  For profiling and benchmarking, it would be useful if the jsc command-line tool exposed this functionality to JavaScript programs.
