From 64ce4c2f5252f25798117fa80a027993163d6d84 Mon Sep 17 00:00:00 2001 From: John Stultz Date: Thu, 11 Mar 2010 14:04:47 -0800 Subject: [PATCH] time: Clean up warp_clock() warp_clock() currently accesses timekeeping internal state directly, which is unnecessary. Convert it to use the proper timekeeping interfaces.
