Detailed Description

The following constants are related to the time of day and are independent of RTEMS.

This handler encapsulates functionality used to manage time of day.

Macro Definition Documentation

◆ TOD_DAYS_PER_YEAR

#define TOD_DAYS_PER_YEAR (uint32_t)365

This constant represents the number of days in a non-leap year.

◆ TOD_HOURS_PER_DAY

#define TOD_HOURS_PER_DAY (uint32_t)24

This constant represents the number of hours per day.

◆ TOD_MICROSECONDS_PER_SECOND

#define TOD_MICROSECONDS_PER_SECOND (uint32_t)1000000

This constant represents the number of microseconds in a second.

◆ TOD_MILLISECONDS_PER_SECOND

#define TOD_MILLISECONDS_PER_SECOND (uint32_t)1000

This constant represents the number of millisecond in a second.

◆ TOD_MINUTES_PER_HOUR

#define TOD_MINUTES_PER_HOUR (uint32_t)60

This constant represents the number of minutes per hour.

◆ TOD_MONTHS_PER_YEAR

#define TOD_MONTHS_PER_YEAR (uint32_t)12

This constant represents the number of months in a year.

◆ TOD_NANOSECONDS_PER_MICROSECOND

#define TOD_NANOSECONDS_PER_MICROSECOND (uint32_t)1000

This constant represents the number of nanoseconds in a mircosecond.

◆ TOD_NANOSECONDS_PER_SECOND

#define TOD_NANOSECONDS_PER_SECOND (uint32_t)1000000000

This constant represents the number of nanoseconds in a second.

◆ TOD_SECONDS_PER_DAY

#define TOD_SECONDS_PER_DAY

Value:

(uint32_t) (TOD_SECONDS_PER_MINUTE * \
                                TOD_MINUTES_PER_HOUR   * \
                                TOD_HOURS_PER_DAY)

This constant represents the number of seconds in a day which does not include a leap second.

◆ TOD_SECONDS_PER_MINUTE

#define TOD_SECONDS_PER_MINUTE (uint32_t)60

This constant represents the number of seconds in a minute.

◆ TOD_SECONDS_PER_NON_LEAP_YEAR

#define TOD_SECONDS_PER_NON_LEAP_YEAR (365 * TOD_SECONDS_PER_DAY)

This constant represents the number of seconds in a non-leap year.

◆ TOD_TICKS_PER_SECOND

#define TOD_TICKS_PER_SECOND TOD_TICKS_PER_SECOND_method()

Gets number of ticks in a second.

This method exists to hide the fact that TOD_TICKS_PER_SECOND can not be implemented as a macro in a .h file due to visibility issues. The Configuration Table is not available to SuperCore .h files but is available to their .c files.

Function Documentation

◆ _TOD_Adjust()

void _TOD_Adjust ( const struct timespec * delta )

Adjust the Time of Time.

This method is used to adjust the current time of day by the specified amount.

Parameters

[in] delta is the amount to adjust

◆ _TOD_Get_timeval()

RTEMS_INLINE_ROUTINE void _TOD_Get_timeval ( struct timeval * time )

This routine returns a timeval based upon the internal timespec format TOD.

◆ _TOD_Is_set()

RTEMS_INLINE_ROUTINE bool _TOD_Is_set ( void )

Check if the TOD is Set.

Returns: TRUE is the time is set. FALSE otherwise.

◆ _TOD_Set()

void _TOD_Set	(	const struct timespec *	tod,
		ISR_lock_Context *	lock_context
	)

Sets the time of day.

The caller must be the owner of the TOD lock.
