[webkit-dev] PSA: higher precision event timestamp landing soon - port verification needed

[Benjamin Poulain]

Hi WebKit,

Next week, I will land a patch changing the way event timestamps are
handled: https://bugs.webkit.org/show_bug.cgi?id=117179

Previously, the PlatformEvent timestamp was ignored when creating a DOM
Event, and a new timestamp was generated with currentTime() when the DOM
Event was created.
After the change, the timestamp from the PlatformEvent is used for the DOM
Event.

This change will help web pages to determine the speed and acceleration of
input with a better accuracy.

The patch of https://bugs.webkit.org/show_bug.cgi?id=117179 updates the Mac
port to adapt for the changes. The other ports may need to be changed as
well.
Please take a minute to check your port, and create a bug blocking 117179
if needed.
The timestamp passed to create PlatformEvents must now be the time in
seconds since Unix Epoch.

Benjamin
