From df8e3029f933bbbdb3c20edfd26d37ec6722d7ae Mon Sep 17 00:00:00 2001 From: Micael Karlberg Date: Tue, 10 Jul 2012 16:45:43 +0200 Subject: Fixed problem with TimeTicks decode The decoder had a problem with data of type TimeTicks. Also, the handling of invalid values (value out of range) was bad for both TimeTicks and Unsigned32.
