CHANGES HAVE BEEN MADE TO SUIT -LIBKUMU STYLE AND TYPE CONVENTIONS. ALL BUGS BELONG TO JOHN HURST. -THE FOLLOWING IS FOR ATTRIBUTION, THANK YOU MR. BERNSTEIN FOR WRITING -AND DISTRIBUTING SUCH GREAT SOFTWARE: - -libtai 0.60, alpha. -19981013 -Copyright 1998 -D. J. Bernstein, djb@pobox.com -http://pobox.com/~djb/libtai.html - - -libtai is a library for storing and manipulating dates and times. - -libtai supports two time scales: (1) TAI64, covering a few hundred -billion years with 1-second precision; (2) TAI64NA, covering the same -period with 1-attosecond precision. Both scales are defined in terms of -TAI, the current international real time standard. - -libtai provides an internal format for TAI64, struct tai, designed for -fast time manipulations. The tai_pack() and tai_unpack() routines -convert between struct tai and a portable 8-byte TAI64 storage format. -libtai provides similar internal and external formats for TAI64NA. - -libtai provides struct caldate to store dates in year-month-day form. It -can convert struct caldate, under the Gregorian calendar, to a modified -Julian day number for easy date arithmetic. - -libtai provides struct caltime to store calendar dates and times along -with UTC offsets. It can convert from struct tai to struct caltime in -UTC, accounting for leap seconds, for accurate date and time display. It -can also convert back from struct caltime to struct tai for user input. -Its overall UTC-to-TAI conversion speed is 100x better than the usual -UNIX mktime() implementation. - -This version of libtai requires a UNIX system with gettimeofday(). It -will be easy to port to other operating systems with compilers -supporting 64-bit arithmetic. - -The libtai source code is in the public domain. - -*/ - - /*! \file KM_tai.h - \version $Id: KM_tai.h,v 1.5 2012/02/21 02:09:30 jhurst Exp $ - \brief portable time functions - */ - -#ifndef _KUMU_TAI_H_ -#define _KUMU_TAI_H_ - -#include <KM_platform.h> - -// -namespace Kumu -{ - namespace TAI - { - class caltime; - - // - struct tai - { - ui64_t x; - inline void add_seconds(i32_t s) { x += s; } - inline void add_minutes(i32_t m) { x += m * 60; } - inline void add_hours(i32_t h) { x += h * 3600; } - inline void add_days(i32_t d) { x += d * 86400; } - void now(); - - const tai& operator=(const caltime& rhs); - }; - - // - struct caldate - { - i32_t year; - i32_t month; - i32_t day; - }; - - // - class caltime - { - public: - caldate date; - i32_t hour; - i32_t minute; - i32_t second; - i32_t offset; - - const caltime& operator=(const tai& rhs); - }; - - - } // namespace TAI - -} // namespace Kumu - - -#endif // _KUMU_TAI_H_ - -// -// end KM_tai.h -// |
