I'm putting new USC blade servers to production. I've discovered that if I set correct time zone for my city ( "Asia/Yekaterinburg (Moscow+02 Urals)" ), the time shown in USC Manager is one hour behind the actual time. It seems that this bug is related to any Russian time zone. For example, if I select Novosibirsk time zone (Asia/Moscow+3), the system shows correct time for my city, which is one hour behind Novosibirsk time.
USC Manager version is 2.1(1a) (the latest version available for download from Cisco site). The system is set to obtain correct time from NTP server which is local Windows domain controller (which, in turn, syncronizes its time from Internet NTP server).
Switching between summer and winter time in Russia was cancelled two or three years ago. I suspect that Cisco programmers are simply unaware of this fact.
