> Relative timers can be set today using Timer.offset().setRelative(). However 
> there are use cases in which a DoFn needs to maintain the timer timestamp in 
> state and use this as the relative offset (e.g. so it can later update just 
> the output timestamp without modifying the fire timestamp). This is 
> impossible today for several reasons
>    - Processing-time timers disallow set(), only setRelative() is allowed.
>    - There's no way of knowing what the base value for setRelative is. Using 
> the system-provided base value is important as otherwise tests using 
> TestStream will not work correctly.
