Time of day

data TimeOfDay Source #

Time of day as represented in hour, minute and second (with picoseconds), typically used to express local time of day.

Constructors

TimeOfDay

Fields

todHour :: Int
range 0 - 23
todMin :: Int
range 0 - 59
todSec :: Pico
Note that 0 <= todSec < 61, accomodating leap seconds. Any local minute may have a leap second, since leap seconds happen in all zones simultaneously
