Derbyshire were held up by bright sunlight days after they were sunk by torrential rain at the County Ground.
Monday's Twenty20 match against Durham was abandoned without a ball bowled and tonight's home game with Leicestershire was held up seven overs into the contest.
The problem was the setting sun which has interrupted matches at Derby before but a new ECB ruling means that up to an hour can be added on to make up for time lost.
That could see the game still being played at 10.45pm - which would be the latest a game has finished in this country.
Derbyshire Phantoms tried to combat the glare from the sun by replacing the left-handed Travis Birt with the right-handed Greg Smith before a ball was bowled after the Foxes had won the toss.
Smith and Michael Dighton had no problems seeing the ball as they took 31 from the first three overs before Garnett Kruger yorked Dighton for 10.
The Foxes should have removed Smith for 21 off the first ball of the fifth over but HD Ackerman put down an easy chance at short midwicket with James Allenby the unlucky bowler.
It proved costly as Smith drove Allenby from a four and six and was 41 not out from 28 balls when sun stopped play with the home side 63 for one from seven overs.
The match was expected to resume at just after 8.30 with the interval between innings shortened to 10 minutes.
