(1970) </Td> <Td> "Free" (1971) </Td> </Tr> <P> "Does Anybody Really Know What Time It Is?" is a song by the rock band Chicago . It was included on their 1969 debut album Chicago Transit Authority and released as a single in 1970 . The song was written and sung by Robert Lamm . </P> <P> The song was not released as a single until two tracks from the band's second album, "Make Me Smile" and "25 or 6 to 4", had become hits . It became the band's third straight Top 10 single, peaking at number seven in the U.S. and number two in Canada . Because the song straddled years in its chart run, it is not ranked on the major U.S. year - end charts . However, in Canada, where it charted higher, it is ranked as both the 59th biggest hit of 1970 and the 37th biggest hit of 1971 . </P>
