commit 4bb44f2c15b3f9e9b63d229af938e8a321556215 Author: Nick Mathewson <nickm@torproject.org> Date: Fri Mar 25 16:46:02 2016 -0400 Only check in-boundsness of seconds when time_t is smaller than i64 Otherwise coverity complains that we're checking an whether an int64 is less than INT64_MIN, which of course it isn't. Fixes CID 1357176.
