Time of Day

The clock starts at 6:00. It is day between 6:00 to 18:00, and night from 18:00 to 6:00. It takes 12 minutes for a whole day to pass, both day and night last the same time(6 minutes day and 6 minutes night). Currently there is only one way of interrupting this cycle, and it is with Night Stalker's ultimate, Darkness.

Vision
During the night most heroes have restricted vision, the exceptions being Night Stalker with 1200/1800 and Enchantress with 1800/1800, Most other heroes in the game have a day vision of 1800, and a night vision of 800 or atleast a night vision below 1800.
