1. Overload¶

public static IQbservable<long> Timer(this IQbservableProvider provider, DateTimeOffset dueTime)

Summary: Returns an observable sequence that produces a single value at the specified absolute due time.

Parameters

Name	Type	Description
`provider`	[IQbservableProvider](#	Query provider used to construct the [IQbservable](# data source.
`dueTime`	DateTimeOffset	Absolute time at which to produce the value. If this value is less than or equal to DateTimeOffset.UtcNow, the timer will fire as soon as possible.

Returns: IQbservable -- An observable sequence that produces a value at due time.

2. Overload¶

public static IQbservable<long> Timer(this IQbservableProvider provider, DateTimeOffset dueTime, TimeSpan period)

Summary: Returns an observable sequence that periodically produces a value starting at the specified initial absolute due time.

Parameters

Name	Type	Description
`provider`	[IQbservableProvider](#	Query provider used to construct the [IQbservable](# data source.
`dueTime`	DateTimeOffset	Absolute time at which to produce the first value. If this value is less than or equal to DateTimeOffset.UtcNow, the timer will fire as soon as possible.
`period`	TimeSpan	Period to produce subsequent values. If this value is equal to TimeSpan.Zero, the timer will recur as fast as possible.

Returns: IQbservable -- An observable sequence that produces a value at due time and then after each period.

Exceptions

Type	Condition
System.ArgumentOutOfRangeException	`period` is less than TimeSpan.Zero.

3. Overload¶

public static IQbservable<long> Timer(this IQbservableProvider provider, DateTimeOffset dueTime, TimeSpan period, IScheduler scheduler)

Summary: Returns an observable sequence that periodically produces a value starting at the specified initial absolute due time, using the specified scheduler to run timers.

Parameters

Name	Type	Description
`provider`	[IQbservableProvider](#	Query provider used to construct the [IQbservable](# data source.
`dueTime`	DateTimeOffset	Absolute time at which to produce the first value. If this value is less than or equal to DateTimeOffset.UtcNow, the timer will fire as soon as possible.
`period`	TimeSpan	Period to produce subsequent values. If this value is equal to TimeSpan.Zero, the timer will recur as fast as possible.
`scheduler`	[IScheduler](#	Scheduler to run timers on.

Returns: IQbservable -- An observable sequence that produces a value at due time and then after each period.

Exceptions

Type	Condition
System.ArgumentOutOfRangeException	`period` is less than TimeSpan.Zero.
System.ArgumentNullException	`scheduler` is null.

4. Overload¶

public static IQbservable<long> Timer(this IQbservableProvider provider, DateTimeOffset dueTime, IScheduler scheduler)

Summary: Returns an observable sequence that produces a single value at the specified absolute due time, using the specified scheduler to run the timer.

Parameters

Name	Type	Description
`provider`	[IQbservableProvider](#	Query provider used to construct the [IQbservable](# data source.
`dueTime`	DateTimeOffset	Absolute time at which to produce the value. If this value is less than or equal to DateTimeOffset.UtcNow, the timer will fire as soon as possible.
`scheduler`	[IScheduler](#	Scheduler to run the timer on.

Returns: IQbservable -- An observable sequence that produces a value at due time.

Exceptions

Type	Condition
System.ArgumentNullException	`scheduler` is null.

5. Overload¶

public static IQbservable<long> Timer(this IQbservableProvider provider, TimeSpan dueTime)

Summary: Returns an observable sequence that produces a single value after the specified relative due time has elapsed.

Parameters

Name	Type	Description
`provider`	[IQbservableProvider](#	Query provider used to construct the [IQbservable](# data source.
`dueTime`	TimeSpan	Relative time at which to produce the value. If this value is less than or equal to TimeSpan.Zero, the timer will fire as soon as possible.

Returns: IQbservable -- An observable sequence that produces a value after the due time has elapsed.

6. Overload¶

public static IQbservable<long> Timer(this IQbservableProvider provider, TimeSpan dueTime, TimeSpan period)

Summary: Returns an observable sequence that periodically produces a value after the specified initial relative due time has elapsed.

Parameters

`dueTime`	TimeSpan	Relative time at which to produce the first value. If this value is less than or equal to TimeSpan.Zero, the timer will fire as soon as possible.
`period`	TimeSpan	Period to produce subsequent values. If this value is equal to TimeSpan.Zero, the timer will recur as fast as possible.

Returns: IQbservable -- An observable sequence that produces a value after due time has elapsed and then after each period.

Exceptions

Type	Condition
System.ArgumentOutOfRangeException	`period` is less than TimeSpan.Zero.

7. Overload¶

public static IQbservable<long> Timer(this IQbservableProvider provider, TimeSpan dueTime, TimeSpan period, IScheduler scheduler)
