It is expected that these values should not be null or negative however the "start" value is consistently coming up as negative when supplied to the componentWork order tasks have negative start, mid, or end values.For example, have a scheduled travel start that is before the year 1970 and since before 1970 the timestamp value is taken up as negative it causes the calendar to crash.ResolutionMake sure there are no negative values for the start, mid, or end fields of work order tasks
