Description

Summary: Double hexagon numbers
Readability: medium
Examples: 04:36, 12:59, 18:25, 20:47

The time is told in 4 digital numbers, that are created each by two separate hexagons. This separation adds a little crypticness, if you see each hexagon as a unit. Once you passed the barrier of abstraction, it's easy.
