The start times of five Grands Prix, including Australia, Malaysia and Japan, have been brought forward by one hour in the 2015 season.
In a document detailing session times for the 20-race season released by Formula One Management, the events in Australia, Malaysia, China, Japan and Russia all have their races listed with local start times one hour earlier than last year.
Over recent years races in Asia, along with the season-opener in Australia, have been scheduled to start in mid-late afternoon slots so to be more convenient for F1’s core European television audience.
However, change has been afoot since the Accident Panel looking into Jules Bianchi’s horrifying accident in last October’s rain-hit Japanese GP recommended that, excluding bespoke night races, “the start time of an event shall not be less than four hours before either sunset or dusk".
Malaysian GP chiefs indicated last week that they had discussed with Bernie Ecclestone the possibility of their race returning to a 3pm slot from 4pm, and that one-hour shift has duly been confirmed on the FOM list.
Indeed, the first three rounds will start an hour earlier than in 2014 with Australia moved forward to 4pm (5am GMT) from 5pm local time and China's event also moved, from 3pm to 2pm local.
September’s Japanese GP is also now listed to start at 2pm, as will the following race in Russia in a move previously announced by Sochi organisers last week.
