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
BASE_IMPEXP 
mrpt::system::buildTimestampFromParts (const mrpt::system::TTimeParts &p)

mrpt::system::TTimeStamp
BASE_IMPEXP 
mrpt::system::buildTimestampFromPartsLocalTime (const mrpt::system::TTimeParts &p)
 Builds a timestamp from the parts (Parts are in local time) More...
 
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. More...
 
mrpt::system::TTimeStamp
BASE_IMPEXP 
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
BASE_IMPEXP 
mrpt::system::getCurrentLocalTime ()
 Returns the current (local) time. More...
 
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. More...
 
mrpt::system::TTimeStamp
BASE_IMPEXP 
mrpt::system::time_tToTimestamp (const time_t &t)

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 BASE_IMPEXP 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
BASE_IMPEXP 
mrpt::system::timestampAdd (const mrpt::system::TTimeStamp tim, const double num_seconds)

mrpt::system::TTimeStamp
BASE_IMPEXP 
mrpt::system::secondsToTimestamp (const double nSeconds)
 Transform a time interval (in seconds) into TTimeStamp (e.g. More...
 
std::string BASE_IMPEXP mrpt::system::formatTimeInterval (const double timeSeconds)
