Bug ID: 46474
Summary: IE9 implements the Navigation Timing API incorrectly
Product: MediaWiki extensions
Version: unspecified
Hardware: All
OS: All
Status: NEW
Severity: normal
Priority: Unprioritized
Component: NavigationTiming
Assignee: wikibugs-l@lists.wikimedia.org
Reporter: o...@wikimedia.org
Classification: Unclassified
Mobile Platform: ---
The specs from the W3C specify that "if there is no previous document, this
attribute [i.e., navigationStart] must return the same value as fetchStart."
IE9 incorrectly sets the value to 0 when there is no previous document. As a
result, the values for 'loading' and 'sending' are left as epoch timestamps
(rather than time deltas). These overflow INT in MySQL, leaving us with a bunch
of 2147483647 values (equal to max. int).
This appears to have been fixed in IE10.
