From e8276674f3dc77e497ee2600cd45f51e731c6dab Mon Sep 17 00:00:00 2001 From: dwmalone Date: Mon, 23 Jul 2007 09:42:32 +0000 Subject: [PATCH] If clock_ct_to_ts fails to convert time time from the real time clock, print a one line error message. Add some comments on not being able to trust the day of week field (I'll act on these comments in a follow up commit).
