Error when Scheduling a task with cron syntax

When scheduling a task, I get a SqlDateTime overflow error. Has anyone else encountered this (and resolved). Scheduling a task syntax/process I'm using:

/// <summary>
/// Schedule the next instant for the task
/// </summary>
public static void ScheduleTask()

var newTask = new MyCustomScheduledTask

ScheduleSpec = "* * * * * *", // The task will execute Each minute
ScheduleSpecType = "crontab",
Key = "MyUniqueGuidKey"
;

var schedulingManager = SchedulingManager.GetManager();
schedulingManager.AddTask(newTask);
schedulingManager.SaveChanges(); // EXCEPTION THROWN HERE

Exception details:
