[Haskell-cafe] What is the good way to work with list comprehension and UTCTime?

[Magicloud Magiclouds]

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 idea?
