Subject: Don't throw needlessly. Failure of gettimeofday is *very* unlinkely so
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=d8509c95b874bcfe117bbb852ed4335f46d9db77;p=oota-llvm.git

Don't throw needlessly. Failure of gettimeofday is *very* unlinkely so
just return MinTime if that should ever happen.
