This visualization tracks the new day on a minute by minute basis in respect to the rotation of the earth. Usually time is measured by political time zone at 15 degree intervals (7.5 degree intervals in India). These intervals are largely political and do not necessarily represent an accurate moment in time arriving to your geographical location, but rather a point in time common to all.

Based on the notion that 360 degrees of longitude = 24 hours starting and ending at the International date line (180 degrees longitude), we can calculate that each minute is one quarter of a degree. Based on this calculation we may determine (to the closest minute), exactly where the midnight line is experienced at any given longitude.
