Hi,
Simple usage, I could make an instance of Enum to UTCTime, so
[utcTime..] could work. But that is so stiff. How if sometimes I want
to step by 1 min, sometimes I want to step by 1 sec?
So I think some way like [ t | addUTCTime last 60 ] could be nice.
But I cannot figure it out
Any id

Consider using the time-lens package.
import Data.Time.Lens
import Data.Lens.Common
List comprehension style:
[modL seconds (+ fromIntegral n) t | n <- [0..]]
[modL minutes (+ n) t | n <- [0..]]
(you need fromIntegral for seconds, because it is of fractional type in
Data.Time).
iterate
This is nice. Thanks to all.

Antoine has it right, the language is lifted from the RFC.
