Detailed Description

Classes for date and time manipulation.

Classes for date and time manipulation.

Date: Generic date class storing YMD and julian days

Zulu: Very simple time class storing seconds since midnight as a float. Rollover functions are provided to integrate with the Date class. Time is ZULU (UTC), with an optional TZ field that can be used to adjust for the local timezone.

DateZulu: This class simply combines Date and Zulu, implementing date/time rollover. Some astronical time routines, such as MST (GMST/LMST) are implemented.

SimTime: This is nothing more than a typedef to the internal time storage type used by Zulu (currently float).

SimDate: This class combines DateZulu and BaseType so that date and time can be serialized to and from data archives. A simple parsing function for XML cdata streams is also implemented.

Typedef Documentation

typedef double degree_t

typedef double radian_t

typedef DateZulu::time_t SimTime

Simution time (seconds). SimTime is not actually a class, but just a floating point type that stores seconds since midnight.

typedef short sint16

typedef int sint32

typedef double timing_t

typedef unsigned char uint08

Function Documentation

timing_t get_realtime (    )

Return the current time in seconds. The offset is platform dependent, so do not use this value for absolute time.

SIMDATA_EXCEPTION (  InvalidDate    )

Exception thrown by the Date class when invalid dates are detected.

void tend (  void    )

Stop the timer.

void tstart (  void    )

Start the timer.

double tval (    )

Get the time interval (in seconds) between last calls to tstart() and tend(). The precision should be about 1-2 ms on most platforms.
