shevek::absolute_time(3) Library Functions Manual shevek::absolute_time(3) NAME
shevek::absolute_time - The absolute_time class stores a date and time. SYNOPSIS
#include <time.hh> Public Member Functions absolute_time () Create a new absolute_time containing the current time. absolute_time (unsigned years, unsigned months, unsigned days, unsigned hours, unsigned minutes, unsigned seconds, unsigned nanoseconds=0) A specific time. absolute_time (timetype seconds, unsigned nanoseconds) Fast constructor. absolute_time operator+ (relative_time that) const Add an interval to this moment. absolute_time operator- (relative_time that) const Subtract an interval from this moment. relative_time operator- (absolute_time that) const Compute the interval between two moments. absolute_time & operator+= (relative_time that) Add an interval to this moment. absolute_time & operator-= (relative_time that) Subtract an interval from this moment. bool operator< (absolute_time that) const Compare two moments. bool operator> (absolute_time that) const Compare two moments. bool operator<= (absolute_time that) const Compare two moments. bool operator>= (absolute_time that) const Compare two moments. bool operator== (absolute_time that) const Compare two moments. bool operator!= (absolute_time that) const Compare two moments. unsigned nanoseconds () const Get the nanoseconds. unsigned local_second () const Get the seconds in local time. unsigned local_minute () const Get the minutes in local time. unsigned local_hour () const Get the hour in local time. unsigned local_days () const Get the day of the year in local time, range 0-365. unsigned local_day () const Get the day of the month in local time, range 1-31. unsigned local_weekday () const Get the day of the week in local time, range 0-6 where 0 means sunday. unsigned local_month () const Get the month in local time, range 1-12. unsigned local_year () const Get the year in local time. unsigned second () const Get the seconds in UTC. unsigned minute () const Get the minutes in UTC. unsigned hour () const Get the hour in UTC. unsigned days () const Get the day of the year in UTC, range 0-365. unsigned day () const Get the day of the month in UTC, range 1-31. unsigned weekday () const Get the day of the week in UTC, range 0-6 where 0 means sunday. unsigned month () const Get the month in UTC, range 1-12. unsigned year () const Get the year in UTC. timetype total () const Total number of seconds since january 1970, as encoded. sigc::connection schedule (sigc::slot0< void > callback, Glib::RefPtr< Glib::MainContext > context=Glib::MainContext::get_default()) Schedule a callback at a certain time. Static Public Member Functions static absolute_time create_from_local (unsigned years, unsigned months, unsigned days, unsigned hours, unsigned minutes, unsigned seconds, unsigned nanoseconds=0) Semi-constructor which creates a new absolute_time given a date in local time. static void set_digits (unsigned num) Set number of digits to use when printing (for fractions of seconds) static unsigned get_digits () Get the number of digits which is used when printing. Friends sigc::connection schedule (sigc::slot0< void > callback, int prio, Glib::RefPtr< Glib::MainContext > context) Schedule a callback for when the main loop has time. std::ostream & operator<< (std::ostream &s, absolute_time t) Write the time to a std::ostream. Detailed Description The absolute_time class stores a date and time. Everything is in UTC, except the output of local_* (); Constructor &; Destructor Documentation shevek::absolute_time::absolute_time () Create a new absolute_time containing the current time. Note that this makes a call to gettimeofday, which is much slower than specifying seconds and nanoseconds. Thus, if you need an absolute_time object to fill with an actual time later, use absolute_time foo (0, 0); instead of this default constructor. shevek::absolute_time::absolute_time (unsignedyears, unsignedmonths, unsigneddays, unsignedhours, unsignedminutes, unsignedseconds, unsignednanoseconds = 0) A specific time. days may be 0-365, with months 0. If months > 0, both days and months have a base of 1. shevek::absolute_time::absolute_time (timetypeseconds, unsignednanoseconds) Fast constructor. This directly fills the internal structures. It is therefore faster than the other constructors, in particular the default constructor, which makes a kernel call. Member Function Documentation static absolute_time shevek::absolute_time::create_from_local (unsignedyears, unsignedmonths, unsigneddays, unsignedhours, unsignedminutes, unsignedseconds, unsignednanoseconds = 0) [static] Semi-constructor which creates a new absolute_time given a date in local time. The input is the same as for the similar constructor. bool shevek::absolute_time::operator!= (absolute_timethat) const Compare two moments. Note that this is rarely a useful operation, because minor errors may be introduced by computations. In other words: only use this on times which have been set, never on times which have been computed. bool shevek::absolute_time::operator== (absolute_timethat) const Compare two moments. Note that this is rarely a useful operation, because minor errors may be introduced by computations. In other words: only use this on times which have been set, never on times which have been computed.
