We are still missing the .Net method:

`Scheduler.Schedule Method (IScheduler, DateTimeOffset, Action)`

The `DateTimeOffset` object is described as representing "The absolute time at which to execute the action."

This would be pretty straight-forward to implement as an overload in `AbstractScheduler` that takes desired time minus current time and gets the delay to pass to the other methods `delayTime` argument.

We should probably add this before committing so we fully match the .Net interface.
