Subject: timeval: gettimeofday() for Windows.
X-Git-Tag: sliver-openvswitch-2.2.90-1~8^2~2
X-Git-Url: http://git.onelab.eu/?a=commitdiff_plain;h=bae94bc77362b59a52c0f562e62ff96198dab9d0;p=sliver-openvswitch.git

timeval: gettimeofday() for Windows.

Use GetSystemTimePreciseAsFileTime() for gettimeofday().
GetSystemTimePreciseAsFileTime() provides the result that is more
high resolution than just the microsecond that gittimeofday() in
Linux provides. So we need to remove some additional precision.
