DateTime::Format::W3CDTF - Parse and format W3CDTF datetime strings
SYNOPSIS
use DateTime::Format::W3CDTF;
my $w3c = DateTime::Format::W3CDTF->new;
my $dt = $w3c->parse_datetime( '2003-02-15T13:50:05-05:00' );
# 2003-02-15T13:50:05-05:00
$w3c->format_datetime($dt);
DESCRIPTION
This module understands the W3CDTF date/time format, an ISO 8601 profile, defined at http://www.w3.org/TR/NOTE-datetime. This format as
the native date format of RSS 1.0.
It can be used to parse these formats in order to create the appropriate objects.
METHODS
This API is currently experimental and may change in the future.
o new()
Returns a new W3CDTF parser object.
o parse_datetime($string)
Given a W3CDTF datetime string, this method will return a new "DateTime" object.
If given an improperly formatted string, this method may die.
o format_datetime($datetime)
Given a "DateTime" object, this methods returns a W3CDTF datetime string.
NOTE: As of version 0.4, format_datetime no longer attempts to truncate datetimes without a time component. This is due to the fact
that "DateTime" doesn't distinguish between a date with no time component, and midnight.
o format_date($datetime)
Given a "DateTime" object, return a W3CDTF datetime string without the time component.
SUPPORT
Support for this module is provided via the datetime@perl.org email list. See http://datetime.perl.org/?MailingList for details.

DateTime::Format::SQLite - Parse and format SQLite dates and times
SYNOPSIS
use DateTime::Format::SQLite;
my $dt = DateTime::Format::SQLite->parse_datetime( '2003-01-16 23:12:01' );
# 2003-01-16 23:12:01
DateTime::Format::SQLite->format_datetime($dt);
DESCRIPTION
This module understands the formats used by SQLite for its "date", "datetime" and "time" functions. It can be used to parse these formats
in order to create DateTime objects, and it can take a DateTime object and produce a timestring accepted by SQLite.
NOTE: SQLite does not have real date/time types but stores everything as strings. This module deals with the date/time strings as
understood/returned by SQLite's "date", "time", "datetime", "julianday" and "strftime" SQL functions. You will usually want to store your
dates in one of these formats.
METHODS
This class offers the methods listed below. All of the parsing methods set the returned DateTime object's time zone to the UTC zone
because SQLite does always uses UTC for date calculations. This means your dates may seem to be one day off if you convert them to local
time.
o parse_datetime($string)
Given a $string representing a date, this method will return a new "DateTime" object.
The $string may be in any of the formats understood by SQLite's "date", "time", "datetime", "julianday" and "strftime" SQL functions or
it may be in the format returned by these functions (except "strftime", of course).
The time zone for this object will always be in UTC because SQLite assumes UTC for all date calculations.
If $string contains no date, the parser assumes 2000-01-01 (just like SQLite).
If given an improperly formatted string, this method may die.
o parse_date($string)
o parse_time($string)
o parse_julianday($string)
These are aliases for "parse_datetime", for symmetry with "format_*" functions.
o format_date($datetime)
Given a "DateTime" object, this methods returnes a string in the format YYYY-MM-DD, i.e. in the same format SQLite's "date" function
uses.
o format_time($datetime)
Given a "DateTime" object, this methods returnes a string in the format HH:MM:SS, i.e. in the same format SQLite's "time" function
uses.
o format_datetime($datetime)
Given a "DateTime" object, this methods returnes a string in the format YYYY-MM-DD HH:MM:SS, i.e. in the same format SQLite's
"datetime" function uses.
o format_julianday($datetime)
Given a "DateTime" object, this methods returnes a string in the format DDDDDDDDDD, i.e. in the same format SQLite's "julianday"
function uses.
