- The header <time.h> defines two macros, and declares several types and
- functions for manipulating time. Many functions deal with a calendar time
- that represents the current date (according to the Gregorian calendar) and
- time. Some functions deal with local time, which is the calendar time
- expressed for some specific time zone, and with Daylight Saving Time, which
- is a temporary change in the algorithm for determining local time. The local
- time zone and Daylight Saving Time are implementation-defined.
-
- The macros defined are NULL; and CLOCKS_PER_SEC which expands to an
- expression with type clock_t (described below) that is the number per second
- of the value returned by the clock function.
-
- The types declared are size_t along with clock_t and time_t which are
- arithmetic types capable of representing times; and struct tm which holds
- the components of a calendar time, called the broken-down time.
-
- The range and precision of times representable in clock_t and time_t are
- implementation-defined. The tm structure shall contain at least the following
- members, in any order. The semantics of the members and their normal ranges
- are expressed in the comments.
- - int tm_sec; // seconds after the minute - [0, 60]
- - int tm_min; // minutes after the hour - [0, 59]
- - int tm_hour; // hours since midnight - [0, 23]
- - int tm_mday; // day of the month - [1, 31]
- - int tm_mon; // months since January - [0, 11]
- - int tm_year; // years since 1900
- - int tm_wday; // days since Sunday - [0, 6]
- - int tm_yday; // days since January 1 - [0, 365]
- - int tm_isdst; // Daylight Saving Time flag
-
- The value of tm_isdst is positive if Daylight Saving Time is in effect, zero
- if Daylight Saving Time is not in effect, and negative if the information
- is not available.
-
- The following macros are defined in this file:<BR>
- @verbatim
- NULL
- CLOCKS_PER_SEC The number of values per second returned by the clock function.
- @endverbatim
-
- The following types are defined in this file:<BR>
- @verbatim
- size_t Unsigned integer type of the result of the sizeof operator.
- clock_t Arithmetic type capable of representing a time from the clock function.
- time_t Arithmetic type capable of representing a time.
- struct tm Holds the components of a calendar time; or broken-down time.

- alternative numeric symbols.
-
- %g, %G, and %V give values according to the ISO 8601 week-based year. In
- this system, weeks begin on a Monday and week 1 of the year is the week
- that includes January 4th, which is also the week that includes the first
- Thursday of the year, and is also the first week that contains at least
- four days in the year. If the first Monday of January is the 2nd, 3rd, or
- 4th, the preceding days are part of the last week of the preceding year;
- thus, for Saturday 2nd January 1999, %G is replaced by 1998 and %V is
- replaced by 53. If December 29th, 30th, or 31st is a Monday, it and any
- following days are part of week 1 of the following year. Thus, for Tuesday
- 30th December 1997, %G is replaced by 1998 and %V is replaced by 01.
-
- If a conversion specifier is not one of the above, the behavior is undefined.
-
- In the "C" locale, the E and O modifiers are ignored and the replacement
- strings for the following specifiers are:
- %a the first three characters of %A.
- %A one of "Sunday", "Monday", ... , "Saturday".
- %b the first three characters of %B.
- %B one of "January", "February", ... , "December".
- %c equivalent to "%a %b %e %T %Y".
- %p one of "AM" or "PM".
- %r equivalent to "%I:%M:%S %p".
- %x equivalent to "%m/%d/%y".
- %X equivalent to %T.
- %Z implementation-defined.
-
- @param s Pointer to the buffer in which to store the result.
- @param maxsize Maximum number of characters to put into buffer s.
- @param format Format string, as described above.
- @param timeptr Pointer to a broken-down time structure containing the
- time to format.
-
- @return If the total number of resulting characters including the
- terminating null character is not more than maxsize, the
- strftime function returns the number of characters placed into
- the array pointed to by s not including the terminating null
- character. Otherwise, zero is returned and the contents of the
- array are indeterminate.
