I'm tempted to say that John Wyndham's short stories are better than his novels. The ten in this collection range from average to awesome. You've got robots, time travel, space travel, and Martians, all written in Wyndham's accessible British style. A couple of them could easily have been made into Twilight Zone episodes. Seeds of Time won't make you forget Day of the Triffids or Midwich Cuckoos but it's definitely worth a read.
