[Live-devel] Patch : clock changing issue

[Rawling, Stuart]

>> "clock_gettime()" does not seem to be portable. (In particular, Mac OS X
doesn't seem to have it, and (I suspect) Windows doesn't either.)

The patch does not change the windows implementation other than renaming the
function ³mgettimeofday².   It does a new function mgettimeofday as an #else
(to cover non windows implementations).  All the calls to gettimeofday are
reimplemented as mgettimeofday.  Perhaps the best procedure would be to have
the following: (pseudo code)

#ifdef WIN32 
Int mgettimeofday()
{
  // Normal windows implementation
}
#else 
Int mgettimeofday(){

#ifdef MONOTONIC_CLOCK
// Call clock_gettime() variant
#else
// call regular gettimeofday()
gettimeofday()
#endif
#endif

This could be handled with a compile flag that is defined in the
config.linux and config.linux-gdb configurations.   I see the 100% cpu
whenever the time jumps back.  The cpu max out continues until the time
catches up.  This definitely seems to fix it.

Regards,
Stuart
