osGetTime
osSetTime

Syntax

#include <ultra64.h>
OSTime osGetTime(void);
void osSetTime(OSTime time);

Explanation
The osGetTime and osSetTime functions get and set a real-time counter value. The osGetTime function returns the value of time since the last hard reset. The time is expressed in CPU Count register cycles. For NTSC systems, this counter increments at 45.6375 Mhz and each counter tick represents approximately 21.91 nanoseconds. For PAL systems, this counter increments at 46.5525 Mhz and each counter tick represents approximately 21.48 nanoseconds. When the counter reaches its maximum value, it will roll over to zero and continue.

The osSetTime function sets the real time counter value.

See OS_CYCLES_TO_NSEC for useful macros for converting to and from counter cycle time and nanoseconds or microseconds.

Note that the OSTime type is defined to be u64, so when you use the rmonPrintf tool, specify variables of this type with %llu rather than %i or %u.
