m_jiffy in WallClockSynchronizer

[CL]

Hi,

I've modified the source code of wallclocksynchronizer to read a clock signal from simulink so as to synchronize ns3 and simulink. I also changed the m_jiffy variable to 1000, since my sample time in Simulink is 1us. I was wondering if this is the right way to do it (it's in ns I think)? Is there anything else I need to take care of? So far I've only seen that wall-clock-synchronizer.cc, wall-clock-synchronizer.h and unix-system-condition.cc are relevant and need to be modified.

Thanks
