-
- The eccentricity of Earths orbit contributes about 7.7 minutes of variation to the result. It
- has a period of 1 anomalous year, with zeroes at perihelion and aphelion.
-
- The tilt of Earths rotational axis (obliquity) contributes about 9.9 minutes of variation. It
- has a period of 1/2 tropical year, with zeroes at solstices and equinoxes. The time of Earths
- arrival at these events is influenced by the eccentricity, which causes it to progress along its
- orbital path faster as it approaches perihelion, imposing a 'modulation' on the tropical phase.
-
- The algorithm employed computes the orbital position with respect to perihelion, deriving
- from that a 'velocity correction factor'. The orbital position with respect to the winter solstice
- is then computed, as modulated by that factor. The individual contributions of the obliquity and the
- eccentricity components are then summed, and returned as an integer value in seconds.

- \code #include <time.h> \endcode
- <h3>Introduction to the Time functions</h3>
- This file declares the time functions implemented in \c avr-libc.
-
- The implementation aspires to conform with ISO/IEC 9899 (C90). However, due to limitations of the
- target processor and the nature of its development environment, a practical implementation must
- of necessity deviate from the standard.
-
-
-
- Section 7.23.2.1 clock()
- The type clock_t, the macro CLOCKS_PER_SEC, and the function clock() are not implemented. We
- consider these items belong to operating system code, or to application code when no operating
- system is present.
-
- Section 7.23.2.3 mktime()
- The standard specifies that mktime() should return (time_t) -1, if the time cannot be represented.
- This implementation always returns a 'best effort' representation.
-
- Section 7.23.2.4 time()
- The standard specifies that time() should return (time_t) -1, if the time is not available.
- Since the application must initialize the time system, this functionality is not implemented.
-
- Section 7.23.2.2, difftime()
- Due to the lack of a 64 bit double, the function difftime() returns a long integer. In most cases
- this change will be invisible to the user, handled automatically by the compiler.
-
- Section 7.23.1.4 struct tm
- Per the standard, struct tm->tm_isdst is greater than zero when Daylight Saving time is in effect.
- This implementation further specifies that, when positive, the value of tm_isdst represents
- the amount time is advanced during Daylight Saving time.
-
- Section 7.23.3.5 strftime()
- Only the 'C' locale is supported, therefore the modifiers 'E' and 'O' are ignored.
- The 'Z' conversion is also ignored, due to the lack of time zone name.
-
- In addition to the above departures from the standard, there are some behaviors which are different
- from what is often expected, though allowed under the standard.
-
- There is no 'platform standard' method to obtain the current time, time zone, or
- daylight savings 'rules' in the AVR environment. Therefore the application must initialize
- the time system with this information. The functions set_zone(), set_dst(), and
- set_system_time() are provided for initialization. Once initialized, system time is maintained by
- calling the function system_tick() at one second intervals.
-
- Though not specified in the standard, it is often expected that time_t is a signed integer
- representing an offset in seconds from Midnight Jan 1 1970... i.e. 'Unix time'. This implementation
- uses an unsigned 32 bit integer offset from Midnight Jan 1 2000. The use of this 'epoch' helps to
- simplify the conversion functions, while the 32 bit value allows time to be properly represented
- until Tue Feb 7 06:28:15 2136 UTC. The macros UNIX_OFFSET and NTP_OFFSET are defined to assist in
- converting to and from Unix and NTP time stamps.
-
- Unlike desktop counterparts, it is impractical to implement or maintain the 'zoneinfo' database.
- Therefore no attempt is made to account for time zone, daylight saving, or leap seconds in past dates.
- All calculations are made according to the currently configured time zone and daylight saving 'rule'.
-
- In addition to C standard functions, re-entrant versions of ctime(), asctime(), gmtime() and
- localtime() are provided which, in addition to being re-entrant, have the property of claiming
- less permanent storage in RAM. An additional time conversion, isotime() and its re-entrant version,
- uses far less storage than either ctime() or asctime().
-
- Along with the usual smattering of utility functions, such as is_leap_year(), this library includes
- a set of functions related the sun and moon, as well as sidereal time functions.
