Functions
long long	SimTK::timespecToNs (const timespec &ts)
	Convert a time stored in a timespec struct to the equivalent number of nanoseconds (as a signed quantity). More...
void	SimTK::nsToTimespec (const long long &ns, timespec &ts)
	Given a signed number of nanoseconds, convert that into seconds and leftover nanoseconds in a timespec struct. More...
double	SimTK::nsToSec (const long long &ns)
	Given a count of nanosecond ticks as a signed 64 bit integer, return the same time interval as a double precision floating point number of seconds. More...
long long	SimTK::secToNs (const double &s)
	Given a signed time interval as a double precision floating point number of seconds, return the same time interval as a count of nanosecond ticks in a signed 64 bit integer. More...
double	SimTK::cpuTime ()
	Return the cumulative CPU time in seconds (both kernel and user time) that has been used so far by any of the threads in the currently executing process. More...
double	SimTK::threadCpuTime ()
	Return the total CPU time in seconds (both kernel and user time) that has been used so far by the currently executing thread. More...
long long	SimTK::realTimeInNs ()
	Return current time on the high-resolution interval timer in nanoseconds, as a 64-bit integer count. More...
double	SimTK::realTime ()
	Return current time on the high-resolution interval timer in seconds. More...
void	SimTK::sleepInNs (const long long &ns)
	Sleep for the indicated number of nanoseconds, with the actual precision system dependent but intended to be the best achievable, hopefully less than 5ms in all cases. More...
void	SimTK::sleepInSec (const double &seconds)
	Sleep for the indicated number of seconds, with the actual precision system dependent but intended to be the best achievable, hopefully less than 5ms in all cases. More...
