 Since the Soviet era and even to this day, there have been clock idents shown in most channels of Russia, those include the famous Channel One Analog Clock ident with music changing every 12 hours depending on the time of the day, a CGI Kremlin tower clock shown before news on RTR's Russia 1, with the respective ding-dong sounds, and other clocks from other channels, including digital clocks, with the logo on the bottom, top or elsewhere, or even without it.Certain other channels, like STS, do not broadcast news programs but do show a clock sometimes between programs, at special or scheduled checks or at closedown, though a nightly closedown is rare in Russian channels since most of them are already broadcasting 24 hours a day.After a tragedy, or on a national remembrance day, those clock idents are shown silent and their color may be changed.
