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 I<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.
 
     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
     facade 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.

Iain wished to thank:

*
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.
