The Bangladesh Cricket Board (BCB) confirmed this on Wednesday evening.
Now all the matches, barring the second qualifier and the final, will begin one hour ahead of the previous schedule.
So, the first match of the day will start at 12:30pm in place of 1:30pm, and the second one at 5:30pm instead of 6:30pm.
And, on the single-match day, the game will begin at 4pm.
On Tuesday night, fogs and dew had a serious impact on the match between Gemcon Khulna and Gazi Group Chattogram.
However, there are eight more matches left in the Bangabandhu T20 Cup – four of them, including the final, in the playoff round.
The final of the Bangabandhu T20 Cup will be held on December 18 from 4pm at the Sher-e-Bangla National Cricket Stadium. It will be telecast live on T-Sports.
