Support for 8mhz clock CPUS

[vslinuxdotnet]

Hello,
I test this lib with 8mhz cpu, but don't work.
Seams that only works with 16mhz clock.

I divide /2 this vars:

#define DCFRejectionTime 700/2 	// Pulse-to-Pulse rejection time. 
#define DCFRejectPulseWidth 50/2   // Minimal pulse width
#define DCFSplitTime 180/2	// Specifications distinguishes pulse width 100 ms and 200 ms. In practice we see 130 ms and 230
#define DCFSyncTime 1500/2		// Specifications defines 2000 ms pulse for end of sequence

But don't sync,
What I need to change/do to work with 8mhz ?
Thank you.
