Date::Manip is a date manipulation routines.

SYNOPSIS

use Date::Manip;

$version = DateManipVersion;

$date = ParseDate(@args);
$date = ParseDate($string);
$date = ParseDate($string);

@date = UnixDate($date,@format);
$date = UnixDate($date,@format);

$delta = ParseDateDelta(@args);
$delta = ParseDateDelta($string);
$delta = ParseDateDelta($string);

@str = Delta_Format($delta,$dec,@format);
$str = Delta_Format($delta,$dec,@format);

$recur = ParseRecur($string,$base,$date0,$date1,$flags);
@dates = ParseRecur($string,$base,$date0,$date1,$flags);

$flag = Date_Cmp($date1,$date2);

$d = DateCalc($d1,$d2 [,$errref] [,$del]);

$date = Date_SetTime($date,$hr,$min,$sec);
$date = Date_SetTime($date,$time);

$date = Date_SetDateField($date,$field,$val [,$nocheck]);

$date = Date_GetPrev($date,$dow,$today,$hr,$min,$sec);
$date = Date_GetPrev($date,$dow,$today,$time);

$date = Date_GetNext($date,$dow,$today,$hr,$min,$sec);
$date = Date_GetNext($date,$dow,$today,$time);

$name = Date_IsHoliday($date);

$listref = Events_List($date);
$listref = Events_List($date0,$date1);

$date = Date_ConvTZ($date);
$date = Date_ConvTZ($date,$from);
$date = Date_ConvTZ($date,"",$to);
$date = Date_ConvTZ($date,$from,$to);

$flag = Date_IsWorkDay($date [,$flag]);

$date = Date_NextWorkDay($date,$off [,$time]);

$date = Date_PrevWorkDay($date,$off [,$time]);

$date = Date_NearestWorkDay($date [,$tomorrowfirst]);

&Date_Init();
&Date_Init("VAR=VAL","VAR=VAL",...);
@list = Date_Init();
@list = Date_Init("VAR=VAL","VAR=VAL",...);

The above routines all check to make sure that Date_Init is called. If it hasnt been, they will call it automatically. As a result, there is usually no need to call Date_Init explicitely unless you want to change some of the config variables (described below). They also do error checking on the input.

The routines listed below are intended primarily for internal use by other Date::Manip routines. They do little or no error checking, and do not explicitely call Date_Init. Those functions are all done in the main Date::Manip routines above.

Because they are significantly faster than the full Date::Manip routines, they are available for use with a few caveats. Since little or no error checking is done, it is the responsibility of the programmer to ensure that valid data (AND valid dates) are passed to them. Passing invalid data (such as a non-numeric month) or invalid dates (Feb 31) will fail in unpredictable ways (possibly returning erroneous results). Also, since Date_Init is not called by these, it must be called explicitely by the programmer before using these routines.

In the following routines, $y may be entered as either a 2 or 4 digit year (it will be converted to a 4 digit year based on the variable YYtoYYYY described below). Month and day should be numeric in all cases. Most (if not all) of the information below can be gotten from UnixDate which is really the way I intended it to be gotten, but there are reasons to use these (these are significantly faster).

$day = Date_DayOfWeek($m,$d,$y);
$secs = Date_SecsSince1970($m,$d,$y,$h,$mn,$s);
$secs = Date_SecsSince1970GMT($m,$d,$y,$h,$mn,$s);
$days = Date_DaysSince1BC($m,$d,$y);
$day = Date_DayOfYear($m,$d,$y);
($y,$m,$d,$h,$mn,$s) = Date_NthDayOfYear($y,$n);
$days = Date_DaysInYear($y);
$days = Date_DaysInMonth($m,$y);
$wkno = Date_WeekOfYear($m,$d,$y,$first);
$flag = Date_LeapYear($y);
$day = Date_DaySuffix($d);
$tz = Date_TimeZone();

Date::Hijri is a Perl extension to convert islamic (hijri) and gregorian dates.

SYNOPSIS

use Date::Hijri;

# convert gregorian to hijri date
my ($hd, $hm, $hy) = g2h($gd, $gm, $gy);

# convert hijri to gregorian date
my ($gd, $gm, $gy) = h2g($hd, $hm, $hy);

This simple module converts gregorian dates to islamic (hijri) and vice versa.
The dates must be given as an array containing the day, month and year, and return the corresponding date as a list with the same elements.

Date::ICal is a Perl extension for ICalendar date objects.

SYNOPSIS

use Date::ICal;

$ical = Date::ICal->new( ical => 19971024T120000 );
$ical = Date::ICal->new( epoch => time );
$ical = Date::ICal->new( year => 1964,
month => 10, day => 16, hour => 16,
min => 12, sec => 47 );

$hour = $ical->hour;
$year = $ical->year;

$ical_string = $ical->ical;
$epoch_time = $ical->epoch;

$ical2 = $ical + $duration;
(Where $duration is either a duration string, like P2W3DT7H9M, or a Date::ICal::Duration (qv) object.
$ical += P6DT12H;

$duration = $ical1 - $ical2;
$ical3 = $ical1 - $duration;

Date-Pcalc is a Perl module and is a direct translation of Steffen Beyers excellent Date::Calc module to use Perl only instead of a combination of Perl and C.

This package consists of a Perl module for all kinds of date calculations based on the Gregorian calendar (the one used in all western countries today), thereby complying with all relevant norms and standards: ISO/R 2015-1971, DIN 1355 and, to some extent, ISO 8601 (where applicable).

Tk::Date is a date/time widget for perl/Tk.

SYNOPSIS

use Tk::Date;
$date_widget = $top->Date->pack;
$date_widget->get("%x %X");

Tk::Date implements a date/time widget. There are three ways to input a date:
Using the keyboard to input the digits and the tab key or the mouse pointer to move focus between fields.

Using up and down cursor keys to increment/decrement the date (only with installed Tk::NumEntryPlain widget).

Selecting up and down arrow buttons will increment or decrement the value of the active field (only with installed Tk::FireButton widget).

The Date/Time Format

Unlike Java, Perl does not have a date/time object. However, it is possible to use the unix time (seconds since epoch, that is 1st January 1970) as a replacement. This is limited, since on most architectures, the valid range is between 14th December 1901 and 19th January 2038. For other dates, it is possible to use a hash notation:

{ y => year,
m => month,
d => day,
H => hour,
M => minute,
S => second }

The abbreviations are derivated from the format letters of strftime. Note that year is the full year (1998 instead of 98) and month is the real month number, as opposed to the output of localtime(), where the month is subtracted by one.

In this document, the first method will be referred as unixtime and the second method as datehash.

STANDARD OPTIONS

Tk::Date descends from Frame and inherits all of its options.

-orient

Specified orientation of the increment and decrements buttons. May be vertical (default) or horizontal.

Titlebar Date description

Wyrd Date is an addition to the onboard datebook.

It allows you to separate different dates into categories without having to store them in a different program.

What Wyrd Date does is adds a prefix to the beginning of the dates description, you can then list all dates with the same prefix.

It lets you find the appointments you want quicker and easier then before.

Adding a prefix to the dates description it simplifies the look and it takes up less memory.

Requirements:

· Palm III
· Palm OS v3.0

Shows today s date in the form of a Montreal Canadiens jersey. Includes 31 different players. Most of which are part of the Canadiens Hall of Fame. Players include Plante, Carbonneau, Blake, Geoffrion, Lefleur, Richard, and more.

As it seemed wrong not to include Roy, he has been substituted as number 13. It will automatically update when you open Dashboard.

Whats New in This Release:

· Improved graphics to conform to the project at HockeyWidgets.com.
· Fonts and sizes for the names and numbers re-done. Now one fifth the file size.
