Classes
struct	mrpt::system::TTimeParts
	The parts of a date/time (it's like the standard 'tm' but with fractions of seconds). More...
Namespaces
namespace	mrpt
	This is the global namespace for all Mobile Robot Programming Toolkit (MRPT) libraries.
namespace	mrpt::system
	This namespace provides a OS-independent interface to many useful functions: filenames manipulation, time and date, string parsing, file I/O, threading, memory allocation, etc.
Defines
#define	INVALID_TIMESTAMP   (0)
	Represents an invalid timestamp, where applicable.
Time and date functions
typedef uint64_t	mrpt::system::TTimeStamp
	A system independent time type, it holds the the number of 100-nanosecond intervals since January 1, 1601 (UTC).
mrpt::system::TTimeStamp BASE_IMPEXP	mrpt::system::buildTimestampFromParts (const mrpt::system::TTimeParts &p)
	Builds a timestamp from the parts (Parts are in UTC).
mrpt::system::TTimeStamp BASE_IMPEXP	mrpt::system::buildTimestampFromPartsLocalTime (const mrpt::system::TTimeParts &p)
	Builds a timestamp from the parts (Parts are in local time).
void BASE_IMPEXP	mrpt::system::timestampToParts (TTimeStamp t, TTimeParts &p, bool localTime=false)
	Gets the individual parts of a date/time (days, hours, minutes, seconds) - UTC time or local time.
mrpt::system::TTimeStamp BASE_IMPEXP	mrpt::system::getCurrentTime ()
	Returns the current (UTC) system time.
mrpt::system::TTimeStamp	mrpt::system::now ()
	A shortcut for system::getCurrentTime.
mrpt::system::TTimeStamp BASE_IMPEXP	mrpt::system::getCurrentLocalTime ()
	Returns the current (local) time.
mrpt::system::TTimeStamp BASE_IMPEXP	mrpt::system::time_tToTimestamp (const double &t)
	Transform from standard "time_t" (actually a double number, it can contain fractions of seconds) to TTimeStamp.
mrpt::system::TTimeStamp BASE_IMPEXP	mrpt::system::time_tToTimestamp (const time_t &t)
	Transform from standard "time_t" to TTimeStamp.
double BASE_IMPEXP	mrpt::system::timestampTotime_t (const mrpt::system::TTimeStamp &t)
	Transform from TTimeStamp to standard "time_t" (actually a double number, it can contain fractions of seconds).
double BASE_IMPEXP	mrpt::system::timeDifference (const mrpt::system::TTimeStamp &t_first, const mrpt::system::TTimeStamp &t_later)
	Retuns the time difference from t1 to t2 (positive if t2 is posterior to t1), in seconds.
mrpt::system::TTimeStamp BASE_IMPEXP	mrpt::system::secondsToTimestamp (const double &nSeconds)
	Transform a time interval (in seconds) into TTimeStamp (e.g.
std::string BASE_IMPEXP	mrpt::system::formatTimeInterval (const double &timeSeconds)
	Returns a formated string with the given time difference (passed as the number of seconds), as a string [H]H:MM:SS.MILISECS.
std::string BASE_IMPEXP	mrpt::system::dateTimeToString (const mrpt::system::TTimeStamp &t)
	Convert a timestamp into this textual form (UTC time): YEAR/MONTH/DAY,HH:MM:SS.MMM.
std::string BASE_IMPEXP	mrpt::system::dateTimeLocalToString (const mrpt::system::TTimeStamp &t)
	Convert a timestamp into this textual form (in local time): YEAR/MONTH/DAY,HH:MM:SS.MMM.
std::string BASE_IMPEXP	mrpt::system::dateToString (const mrpt::system::TTimeStamp &t)
	Convert a timestamp into this textual form: YEAR/MONTH/DAY.
double BASE_IMPEXP	mrpt::system::extractDayTimeFromTimestamp (const mrpt::system::TTimeStamp &t)
	Returns the number of seconds ellapsed from midnight in the given timestamp.
std::string BASE_IMPEXP	mrpt::system::timeToString (const mrpt::system::TTimeStamp &t)
	Convert a timestamp into this textual form (UTC): HH:MM:SS.MMMMMM.
std::string BASE_IMPEXP	mrpt::system::timeLocalToString (const mrpt::system::TTimeStamp &t, unsigned int secondFractionDigits=6)
	Convert a timestamp into this textual form (in local time): HH:MM:SS.MMMMMM.
std::string BASE_IMPEXP	mrpt::system::intervalFormat (const double seconds)
	This function implements time interval formatting: Given a time in seconds, it will return a string describing the interval with the most appropriate unit.
