The DTM will switch its Misano round to daytime in 2019, having announced uniform start times for its 18-race schedule.
The Italian venue held DTM's first-ever night races under floodlights in August last year, in what was Misano's first season on the schedule.
It has kept its spot for 2019, but the races will no longer run at night, with DTM mandating 1:30pm starts at every race.
The series has also canned its customary race-day practice sessions for 2019.
This means the DTM, which switched to two races per weekend in 2015 and holds a separate qualifying session for each race, will move from three practice sessions to two for each race meeting.
Instead of a practice session on Friday afternoon and one each race-day morning on Saturday and Sunday, it will instead run a pair of sessions on Friday - a 45-minute first FP1 and half-hour FP2.
The series says the change was triggered by an expanded support programme, which will feature the rebranded F3 series Formula European Masters at each event, as well as the new all-female W Series, various Porsche Carrera championships and other categories.
The new weekend format will apply for eight of the championship's nine rounds, with August's Brands Hatch meeting the only exception.
Local noise restrictions at the British venue, which returned to the calendar last year, mean no Friday running will take place. The series will instead revert to race-day practice.
