Subject: Don't move the time threshold for running scheduled events on every iteration.
X-Git-Tag: 1.6.2.12-rc1~21
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ee39dde50e515259674bf7f9e72ad96be9117a12;p=thirdparty%2Fasterisk.git

Don't move the time threshold for running scheduled events on every iteration.

Instead, only calculate the time threshold each time ast_sched_runq() is called.
