Member Function Documentation

DifferenceInMicroseconds()

virtual unsigned long DifferenceInMicroseconds ( unsigned long  sec, unsigned long  usec  )

virtual

Get the difference between a time value and when the "epoch time" began.

Parameters

sec	Time in seconds to compare to "epoch time".
usec	Time in microseconds to compare to "epoch time".

Returns

Return the difference between the time parameters, and the "epoch time", in Microseconds.

DifferenceInSeconds()

virtual double DifferenceInSeconds ( unsigned long  sec, unsigned long  usec  )

virtual

Get the difference between a time value and when the "epoch time" began.

Parameters

sec	Time in seconds to compare to "epoch time"
usec	Time in microseconds to compare to "epoch time"

Returns

Return the difference between the time parameters, and the "epoch time", in Seconds

DIS_Timestamp()

static unsigned long DIS_Timestamp ( )

static

Create a DIS timestamp based on the current time of day.

Returns

Return a DIS timestamp

ElapsedMicroseconds()

virtual unsigned long ElapsedMicroseconds ( )

virtual

Get the number of microseconds elapsed since the "epoch time" began.

Returns

The elapsed Microseconds since the beginning of the epoch.

ElapsedMilliseconds()

virtual unsigned long ElapsedMilliseconds ( )

virtual

Get the number of milliseconds elapsed since the "epoch time" began.

Returns

The elapsed milliseconds since the beginning of the epoch.

ElapsedSeconds()

virtual unsigned long ElapsedSeconds ( )

virtual

Get the number of seconds elapsed since the "epoch time" began.

Returns

The number of seconds since the beginning of the epoch.

ElapsedSecondsDouble()

virtual double ElapsedSecondsDouble ( )

virtual

Get the number of seconds elapsed since the "epoch time" began.

Returns

The number of seconds elapsed since the beginning of the epoch.

GetCurrentTimeInSeconds()

static unsigned long GetCurrentTimeInSeconds ( )

static

Get the number of seconds elapsed since 01/01/1970, "wall clock".

Returns

Return the number of seconds.

GetTimeOfDay() [1/2]

static void GetTimeOfDay ( INT_64 *  usec )

static

Get number of microseconds elapsed since 01/01/1970.

Parameters

usec	Return number of microseconds elapsed.

GetTimeOfDay() [2/2]

static void GetTimeOfDay ( unsigned long *  sec, unsigned long *  usec  )

static

Get the number of seconds elapsed since 01/01/1970, and the number of microseconds elapsed in the current second.

Parameters

sec	Return the number of seconds elapsed since 01/01/1970
usec	Return the fractional second in microseconds

WaitMicroseconds()

static void WaitMicroseconds ( unsigned long  micro )

static

Cause the process (or thread) to sleep for the specified number of microseconds. Clock time continues, this pauses the thread, not the clock.

Parameters

micro

How long to sleep im micoseconds.

WaitMilliseconds()

static void WaitMilliseconds ( unsigned long  milli )

static

Cause the process (or thread) to sleep for the specified number of milliseconds. Clock time continues, this pauses the thread, not the clock.

Parameters

milli

How long to sleep in milliseconds.
