(VCL) Timer vs. SalTimer

[Rodolfo]

Hi.

Can you help me understand why this separation? Why not only SalTimer?

I can't see any advantage in reencapsulate SalTimer.beside the getter
and setters (timeout value and callback) that could be in SalTimer
itself.

The callback signature seems different (sal uses a void return, vcl a
long as returned value). Anyway, the long value is never used
internally on VCL Timer.

Regards.
