Just yesterday, Russian cosmonaut Oleg Kononenko surpassed an earlier record for the amount of time a human has spent in space. He has now been in orbit more than 878 days, this being his fifth rotation on the International Space Station. The earlier record was set in 2015 by cosmonaut Gennady Padalka.
American astronauts have a ways to go before approaching this record. To date, the record for cumulative days in space is held by a NASA astronaut Peggy Whitson at 675 days.
