Classes
struct	mrpt::system::TTimeParts
	The parts of a date/time (it's like the standard 'tm' but with fractions of seconds). More...

Namespaces
	mrpt
	This is the global namespace for all Mobile Robot Programming Toolkit (MRPT) libraries.
	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.

Macros
#define	INVALID_TIMESTAMP   (0)
	Represents an invalid timestamp, where applicable. More...

Typedefs
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). More...

Functions
mrpt::system::TTimeStamp	mrpt::system::buildTimestampFromParts (const mrpt::system::TTimeParts &p)
	Builds a timestamp from the parts (Parts are in UTC) More...
mrpt::system::TTimeStamp	mrpt::system::buildTimestampFromPartsLocalTime (const mrpt::system::TTimeParts &p)
	Builds a timestamp from the parts (Parts are in local time) More...
void	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. More...
mrpt::system::TTimeStamp	mrpt::system::getCurrentTime ()
	Returns the current (UTC) system time. More...
mrpt::system::TTimeStamp	mrpt::system::now ()
	A shortcut for system::getCurrentTime. More...
mrpt::system::TTimeStamp	mrpt::system::getCurrentLocalTime ()
	Returns the current (local) time. More...
mrpt::system::TTimeStamp	mrpt::system::time_tToTimestamp (const double t)
	Transform from standard "time_t" (actually a double number, it can contain fractions of seconds) to TTimeStamp. More...
mrpt::system::TTimeStamp	mrpt::system::time_tToTimestamp (const time_t &t)
	Transform from standard "time_t" to TTimeStamp. More...
double	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). More...
double	mrpt::system::timestampToDouble (const mrpt::system::TTimeStamp t)
	Transform from TTimeStamp to standard "time_t" (actually a double number, it can contain fractions of seconds). More...
double	mrpt::system::timeDifference (const mrpt::system::TTimeStamp t_first, const mrpt::system::TTimeStamp t_later)
	Returns the time difference from t1 to t2 (positive if t2 is posterior to t1), in seconds. More...
double	mrpt::system::now_double ()
	Returns the current time, as a double (fractional version of time_t) instead of a TTimeStamp. More...
mrpt::system::TTimeStamp	mrpt::system::timestampAdd (const mrpt::system::TTimeStamp tim, const double num_seconds)
	Shifts a timestamp the given amount of seconds (>0: forwards in time, <0: backwards) More...
mrpt::system::TTimeStamp	mrpt::system::secondsToTimestamp (const double nSeconds)
	Transform a time interval (in seconds) into TTimeStamp (e.g. More...
std::string	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. More...
std::string	mrpt::system::dateTimeToString (const mrpt::system::TTimeStamp t)
	Convert a timestamp into this textual form (UTC time): YEAR/MONTH/DAY,HH:MM:SS.MMM. More...
std::string	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. More...
std::string	mrpt::system::dateToString (const mrpt::system::TTimeStamp t)
	Convert a timestamp into this textual form: YEAR/MONTH/DAY. More...
double	mrpt::system::extractDayTimeFromTimestamp (const mrpt::system::TTimeStamp t)
	Returns the number of seconds ellapsed from midnight in the given timestamp. More...
std::string	mrpt::system::timeToString (const mrpt::system::TTimeStamp t)
	Convert a timestamp into this textual form (UTC): HH:MM:SS.MMMMMM. More...
std::string	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. More...
std::string	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. More...
