ID: 13090 Title: Fixed 'transitions' and 'next_transition' columns in timeperiods table. Component: Livestatus Level: 1 Class: Bug fix Version: 2.1.0i1 Both columns didn't take the local time zone offset into account. Furthermore, 'next_transition' was off by a factor of 1e9, leading to funny 32bit overflow effects most of the time.
