timed events

[Liquid_Crystal]

Can anyone suggest a good way to incorporate timed events with manual events?  I want to do on-demand sampling , saving, archiving, etc as well as programmatically timed events.

Please see the attached example. There must be a better way.

Take a look the producer/consumer design pattern with events and the one called data.

One is using events, the other polling.

 They are quite similar.

Some events can be replaced by notifiers and queues also.
