Public Member Functions
mrs_natural	getMicroSeconds ()
	get the system microseconds count
mrs_natural	intervalsize (std::string interval)
	convert the given interval into a number of micro seconds.
mrs_natural	readTimeSrc ()
	get the difference between the current source control value and its value since it was last read. Does not currently work for Windows TODO! architecture as it relies on the Unix function gettimeofday().

	copy constructor
	TmRealTime (std::string name)
	named constructor. Given the identifier "TmRealTime/name"
	TmRealTime ()
	empty constructor. Given the default name: System as in "TmRealTime/System"
void	updtime ()
	updtime from TmTimer is overridden to directly set the cur_time_ with the system time rather than an offset since last read. This should avoid possible accumulation of error.
Protected Attributes
int	last_usecs_
	last read count of microseconds.

Member Function Documentation

mrs_natural getMicroSeconds

(

)

get the system microseconds count

Returns:

the microseconds count

Definition at line 47 of file TmRealTime.cpp.

Referenced by TmRealTime::readTimeSrc(), and TmRealTime::updtime().

mrs_natural intervalsize

(

std::string

interval

)

[virtual]

convert the given interval into a number of micro seconds.

The interval must be defined in real time units: us, ms, s, m, h, d.

Parameters:

interval

the interval to calculate

Returns:

the number of micro seconds contained in the interval

Implements TmTimer.

Definition at line 81 of file TmRealTime.cpp.

mrs_natural readTimeSrc

(

)

[virtual]

get the difference between the current source control value and its value since it was last read. Does not currently work for Windows TODO! architecture as it relies on the Unix function gettimeofday().

Returns:

the count since last read

Implements TmTimer.
