[Version 6.0] Hours, Minutes and Seconds not returning RestrictionUnit

[jasonlaw]

Hi,

Any reason why Hours, Minutes and Seconds are not returning RestrictionUnit?
In version 5, we can specify the time to run after the Hours, it is no longer available in version 6.0

        JobManager.AddJob(() => PollModule.ExecutePollReminder(1),
                            run => run
                                    .WithName("PollReminder")
                                    .ToRunEvery(1)
                                    .Hours()
                                    .At(1));  // <-- no longer able in version 6
