+From 7dcdfa9edfc632609b3fc99aabb46a40b0083875 Mon Sep 17 00:00:00 2001

+Subject: [PATCH] Check if _to_secs() returns undef
+
+t/rand_time.t fails when rand_time() returns "00:00:00", since
+_to_secs() then returns 0 which evaluates to false. This happens with a
+probability of about 7 % and was found in an automatic build of the Debian
+packaged version of Data::Random.
