[PATCH weston 05/12] libweston: Use struct timespec for motion events

Alexandros Frantzis alexandros.frantzis at collabora.com
Thu Nov 16 16:20:54 UTC 2017


Change code related to motion events to use struct timespec to represent
time.

This commit is part of a larger effort to transition the Weston codebase
to struct timespec.
