+=head1 NAME
+
+Time::Piece - Object Oriented time objects
+
+=head1 SYNOPSIS
+
+ use Time::Piece;
+
+ my $t = localtime;
+ print "Time is $t\n";
+ print "Year is ", $t->year, "\n";
+
+=head1 DESCRIPTION
+
+This module replaces the standard localtime and gmtime functions with
+implementations that return objects. It does so in a backwards
+compatible manner, so that using localtime/gmtime in the way documented
+in perlfunc will still return what you expect.
+
+The module actually implements most of an interface described by
+Larry Wall on the perl5-porters mailing list here:
+http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2000-01/msg00241.html
+
+=head1 USAGE
+
+After importing this module, when you use localtime or gmtime in a scalar
+context, rather than getting an ordinary scalar string representing the
+date and time, you get a Time::Piece object, whose stringification happens
+to produce the same effect as the localtime and gmtime functions. There is
+also a new() constructor provided, which is the same as localtime(), except
+when passed a Time::Piece object, in which case it's a copy constructor. The
+following methods are available on the object:
+
+ $t->sec # also available as $t->second
+ $t->min # also available as $t->minute
+ $t->hour # 24 hour
+ $t->mday # also available as $t->day_of_month
+ $t->mon # 1 = January
+ $t->_mon # 0 = January
+ $t->monname # Feb
+ $t->month # same as $t->monname
+ $t->fullmonth # February
+ $t->year # based at 0 (year 0 AD is, of course 1 BC)
+ $t->_year # year minus 1900
+ $t->yy # 2 digit year
+ $t->wday # 1 = Sunday
+ $t->_wday # 0 = Sunday
+ $t->day_of_week # 0 = Sunday
+ $t->wdayname # Tue
+ $t->day # same as wdayname
+ $t->fullday # Tuesday
+ $t->yday # also available as $t->day_of_year, 0 = Jan 01
+ $t->isdst # also available as $t->daylight_savings
+
+ $t->hms # 12:34:56
+ $t->hms(".") # 12.34.56
+ $t->time # same as $t->hms
+
+ $t->ymd # 2000-02-29
+ $t->date # same as $t->ymd
+ $t->mdy # 02-29-2000
+ $t->mdy("/") # 02/29/2000
+ $t->dmy # 29-02-2000
+ $t->dmy(".") # 29.02.2000
+ $t->datetime # 2000-02-29T12:34:56 (ISO 8601)
+ $t->cdate # Tue Feb 29 12:34:56 2000
+ "$t" # same as $t->cdate
+
+ $t->epoch # seconds since the epoch
+ $t->tzoffset # timezone offset in a Time::Seconds object
+
+ $t->julian_day # number of days since Julian period began
+ $t->mjd # modified Julian date (JD-2400000.5 days)
+
+ $t->week # week number (ISO 8601)
+
+ $t->is_leap_year # true if it its
+ $t->month_last_day # 28-31
+
+ $t->time_separator($s) # set the default separator (default ":")
+ $t->date_separator($s) # set the default separator (default "-")
+ $t->day_list(@days) # set the default weekdays
+ $t->mon_list(@days) # set the default months
+
+ $t->strftime(FORMAT) # same as POSIX::strftime (without the overhead
+ # of the full POSIX extension)
+ $t->strftime() # "Tue, 29 Feb 2000 12:34:56 GMT"
+
+ Time::Piece->strptime(STRING, FORMAT)
+ # see strptime man page. Creates a new
+ # Time::Piece object
+
+=head2 Local Locales
+
+Both wdayname (day) and monname (month) allow passing in a list to use
+to index the name of the days against. This can be useful if you need
+to implement some form of localisation without actually installing or
+using locales.
+
+ my @days = qw( Dimanche Lundi Merdi Mercredi Jeudi Vendredi Samedi );
+
+ my $french_day = localtime->day(@days);
+
+These settings can be overriden globally too:
+
+ Time::Piece::day_list(@days);
+
+Or for months:
+
+ Time::Piece::mon_list(@months);
+
+And locally for months:
+
+ print localtime->month(@months);
+
+=head2 Date Calculations
+
+It's possible to use simple addition and subtraction of objects:
+
+ use Time::Seconds;
+
+ my $seconds = $t1 - $t2;
+ $t1 += ONE_DAY; # add 1 day (constant from Time::Seconds)
+
+The following are valid ($t1 and $t2 are Time::Piece objects):
+
+ $t1 - $t2; # returns Time::Seconds object
+ $t1 - 42; # returns Time::Piece object
+ $t1 + 533; # returns Time::Piece object
+
+However adding a Time::Piece object to another Time::Piece object
+will cause a runtime error.
+
+Note that the first of the above returns a Time::Seconds object, so
+while examining the object will print the number of seconds (because
+of the overloading), you can also get the number of minutes, hours,
+days, weeks and years in that delta, using the Time::Seconds API.
+
+=head2 Date Comparisons
+
+Date comparisons are also possible, using the full suite of "<", ">",
+"<=", ">=", "<=>", "==" and "!=".
+
+=head2 Date Parsing
+
+Time::Piece links to your C library's strptime() function, allowing
+you incredibly flexible date parsing routines. For example:
+
+ my $t = Time::Piece->strptime("Sun 3rd Nov, 1943",
+ "%A %drd %b, %Y");
+
+ print $t->strftime("%a, %d %b %Y");
+
+Outputs:
+
+ Wed, 03 Nov 1943
+
+(see, it's even smart enough to fix my obvious date bug)
+
+For more information see "man strptime", which should be on all unix
+systems.
+
+=head2 YYYY-MM-DDThh:mm:ss
+
+The ISO 8601 standard defines the date format to be YYYY-MM-DD, and
+the time format to be hh:mm:ss (24 hour clock), and if combined, they
+should be concatenated with date first and with a capital 'T' in front
+of the time.
+
+=head2 Week Number
+
+The I<week number> may be an unknown concept to some readers. The ISO
+8601 standard defines that weeks begin on a Monday and week 1 of the
+year is the week that includes both January 4th and the first Thursday
+of the year. In other words, if the first Monday of January is the
+2nd, 3rd, or 4th, the preceding days of the January are part of the
+last week of the preceding year. Week numbers range from 1 to 53.
+
+=head2 Global Overriding
+
+Finally, it's possible to override localtime and gmtime everywhere, by
+including the ':override' tag in the import list:
+
+ use Time::Piece ':override';

+ * Year/day algorithm notes:
+ *
+ * With a suitable offset for numeric value of the month, one can find
+ * an offset into the year by considering months to have 30.6 (153/5) days,
+ * using integer arithmetic (i.e., with truncation). To avoid too much
+ * messing about with leap days, we consider January and February to be
+ * the 13th and 14th month of the previous year. After that transformation,
+ * we need the month index we use to be high by 1 from 'normal human' usage,
+ * so the month index values we use run from 4 through 15.
+ *
+ * Given that, and the rules for the Gregorian calendar (leap years are those
+ * divisible by 4 unless also divisible by 100, when they must be divisible
+ * by 400 instead), we can simply calculate the number of days since some
+ * arbitrary 'beginning of time' by futzing with the (adjusted) year number,
+ * the days we derive from our month index, and adding in the day of the
+ * month. The value used here is not adjusted for the actual origin which
+ * it normally would use (1 January A.D. 1), since we're not exposing it.
+ * We're only building the value so we can turn around and get the
+ * normalised values for the year, month, day-of-month, and day-of-year.
+ *
+ * For going backward, we need to bias the value we're using so that we find
+ * the right year value. (Basically, we don't want the contribution of
+ * March 1st to the number to apply while deriving the year). Having done
+ * that, we 'count up' the contribution to the year number by accounting for
+ * full quadracenturies (400-year periods) with their extra leap days, plus
+ * the contribution from full centuries (to avoid counting in the lost leap
+ * days), plus the contribution from full quad-years (to count in the normal
+ * leap days), plus the leftover contribution from any non-leap years.
+ * At this point, if we were working with an actual leap day, we'll have 0
+ * days left over. This is also true for March 1st, however. So, we have
+ * to special-case that result, and (earlier) keep track of the 'odd'
+ * century and year contributions. If we got 4 extra centuries in a qcent,
+ * or 4 extra years in a qyear, then it's a leap day and we call it 29 Feb.
+ * Otherwise, we add back in the earlier bias we removed (the 123 from
+ * figuring in March 1st), find the month index (integer division by 30.6),
+ * and the remainder is the day-of-month. We then have to convert back to
+ * 'real' months (including fixing January and February from being 14/15 in
+ * the previous year to being in the proper year). After that, to get
+ * tm_yday, we work with the normalised year and get a new yearday value for
+ * January 1st, which we subtract from the yearday value we had earlier,
+ * representing the date we've re-built. This is done from January 1
+ * because tm_yday is 0-origin.
+ *
+ * Since POSIX time routines are only guaranteed to work for times since the
+ * UNIX epoch (00:00:00 1 Jan 1970 UTC), the fact that this algorithm
+ * applies Gregorian calendar rules even to dates before the 16th century
+ * doesn't bother me. Besides, you'd need cultural context for a given
+ * date to know whether it was Julian or Gregorian calendar, and that's
+ * outside the scope for this routine. Since we convert back based on the
+ * same rules we used to build the yearday, you'll only get strange results
+ * for input which needed normalising, or for the 'odd' century years which
+ * were leap years in the Julian calander but not in the Gregorian one.
+ * I can live with that.
+ *
+ * This algorithm also fails to handle years before A.D. 1 gracefully, but
+ * that's still outside the scope for POSIX time manipulation, so I don't
+ * care.

+Time::Piece
+===========
+
+This module supercedes Time::Object (and has a better name).
+
+At this time the module is almost identical to Time::Object, with
+the exception of strptime support. People using Time::Object should
+migrate over to Time::Piece as they are able to do so. No further
+development will occur to Time::Object.
+
+DESCRIPTION
+
+Have you ever thought you time was thoroughly wasted by doing:
+
+ $ perldoc -f localtime
+
+just to recall the position of wday or some other item in the returned
+list of values from localtime (or gmtime) ?
+
+Well Time::Piece is the answer to your prayers.
+
+Time::Piece does the right thing with the return value from localtime:
+
+ - in list context it returns a list of values
+
+ - in scalar context it returns a Time::Piece object
+
+ - when stringified (or printed), Time::Piece objects look like
+ the output from scalar(localtime)
+
+Beyond that, Time::Piece objects allow you to get any part of the
+date/time via method calls, plus they allow you to get at the string
+form of the week day and month. It has methods for julian days, and
+some simple date arithmetic options.
+
+Time::Piece also gives you easy access to your C library's strftime
+and strptime functions, so you can parse and output locale sensitive
+dates to your heart's content :-)

+=head1 NAME
+
+Time::Seconds - a simple API to convert seconds to other date values
+
+=head1 SYNOPSIS
+
+ use Time::Piece;
+ use Time::Seconds;
+
+ my $t = localtime;
+ $t += ONE_DAY;
+
+ my $t2 = localtime;
+ my $s = $t - $t2;
+
+ print "Difference is: ", $s->days, "\n";
+
+=head1 DESCRIPTION
+
+This module is part of the Time::Piece distribution. It allows the user
+to find out the number of minutes, hours, days, weeks or years in a given
+number of seconds. It is returned by Time::Piece when you delta two
+Time::Piece objects.
+
+Time::Seconds also exports the following constants:
+
+ ONE_DAY
+ ONE_WEEK
+ ONE_HOUR
+ ONE_MINUTE
+ ONE_MONTH
+ ONE_YEAR
+ ONE_FINANCIAL_MONTH
+ LEAP_YEAR
+ NON_LEAP_YEAR
+
+Since perl does not (yet?) support constant objects, these constants are in
+seconds only, so you cannot, for example, do this: C<print ONE_WEEK-E<gt>minutes;>
+
+=head1 METHODS
+
+The following methods are available:
+
+ my $val = Time::Seconds->new(SECONDS)
+ $val->seconds;
+ $val->minutes;
+ $val->hours;
+ $val->days;
+ $val->weeks;
+ $val->months;
+ $val->financial_months; # 30 days
+ $val->years;
+
+The methods make the assumption that there are 24 hours in a day, 7 days in
+a week, 365.24225 days in a year and 12 months in a year.
