 Given a time stamp `fromTime`, return a slice of `n` closest following time stamps which match the cron expression `cronexpr`. The time stamps in the returned slice are in chronological ascending order. The `time.Location` of the returned time stamps is the same as `fromTime`.

-Returns `true` if time stamp `t` is not a valid time stamp from `CronExpression` point of view. An invalid time stamp is returned by this library whenever no matching time stamp is found given a specific cron expression.
