How often should we call OnTimer. Value of 0 means to call OnTimer in every Update event.

Published property OnTimer: TNotifyEvent read FOnTimer write FOnTimer;

The event called periodically.

Published property CounteractDelays: boolean read FCounteractDelays write FCounteractDelays default false;

Should we counteract the delays in timer by firing next event sooner. This helps to keep a constant frequency of timer events over a long time, and to keep multiple things (like multiple timer instances) perfectly synchronized with each other. But it may cause to execute a lot of timer events at once, in case the application hung for some time.
