NAME ^

DateTime::Format::IBeat - Format times in .beat notation

DESCRIPTION ^

No Time Zones

No Geographical Borders

How long is a Swatch .beat? In short, we have divided up the virtual and real day into 1000 beats. One Swatch beat is the equivalent of 1 minute 26.4 seconds. That means that 12 noon in the old time system is the equivalent of @500 Swatch .beats.

Okay, so how can a surfer in New York, or a passenger on a transatlantic flight know when it is @500 Swatch .beats in Central Europe for example? How can the New York surfer make a date for a chat with his cyber friend in Rome? Easy, Internet Time is the same all over the world.(see converter)

How is this possible? We are not just creating a new way of measuring time, we are also creating a new meridian in Biel, Switzerland, home of Swatch.

Biel MeanTime (BMT) is the universal reference for Internet Time. A day in Internet Time begins at midnight BMT (@000 Swatch .beats) (Central European Wintertime). The meridian is marked for all to see on the façade of the Swatch International Headquarters on Jakob-Staempfli Street, Biel, Switzerland. So, it is the same time all over the world, be it night or day, the era of time zones has disappeared.

The BMT meridian was inaugurated on 23 October 1998 in the presence of Nicholas Negroponte, founder and director of the Massachusetts Institute of Technology`s Media Laboratory.

PARSING METHODS ^

parse_time

Parses a .beat time and returns a DateTime object. The object uses the current date for its date and will have UTC set as its timezone. Feel free to use 'set' to convert to your local time.

    my $first = DateTime::Format::IBeat->parse_time( '@765' );
    print $first->datetime; # 2003-04-01T17:21:36

    $first->set_time_zone( "Australia/Sydney" );
    print $first->datetime; # 2003-04-02T03:21:36

Note that the leading @ is optional. Also, if using direct strings, and leading @s, be careful to not have it interpolate it as an array by accident.

parse_date

Parses an .beat date and returns a DateTime object representing that date.

     my $dt = DateTime::Format::IBeat->parse_date('@d01.04.03');
     print $dt->ymd('.'); # "2003.04.01"

Note: this assumes the number of .beats elapsed in the day to be 0, thus it will appear to be returning the day before. If you display a full time with it, you will find it's at UTC rather than BMT (+0100), thus 11pm the day before. The important thing to remember is that it is an accurate conversion to the usual notation, despite appearances.

parse_datetime

Parses an ibeat datetime string and returns a DateTime object representing that datetime.

    my $dt = DateTime::Format::IBeat->parse_datetime(
        '@d01.04.03 @765');
    print $dt->datetime; # "2003-04-01T17:21:36"

FORMATTING METHODS ^

format_time

Given a DateTime object, returns a string representating that time in ibeats.

format_date

Given a DateTime object, returns a string representating that date.

format_datetime

Given a Datetime object, returns a string representating that date and time in .beats format.

THANKS ^

Dave Rolsky (DROLSKY) for kickstarting the DateTime project.

Swatch, for coming up with this mad format.

Jerub, from opn, who wrote the python original, from which I retain no code. D'oh.

SUPPORT ^
