Detailed Description

BLTime - get time since epoch.

Entire class could be inline, but is not to prevent bad optimization.

NOTE: On Windows the resolution of timems() and timeus() is only a second! On Mac OS X and on Linux they have the corresponding resolutions.

Static Public Member Functions
static long	time ()
	time() returns time in seconds since epoch (1970)
static long	timems ()
	timems() returns the time in milliseconds since epoch (1970)
static long long	timeus ()
	timeus() returns the time in microseconds since epoch (1970)
static void	sleepms (int ms)
	sleepms() will sleep for a specified number of milliseconds.
