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.
THANKS
The original author of this module was Iain Truskett (SPOON). Since his tragically early death, the module has been maintained by Earle Martin (EMARTIN), who would like to dedicate it to his memory.
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.
Here is a list of people and their CPAN id, extracted from various places. These people have either submitted patches or suggestions, or their bug reports or comments have inspired the appropriate patches. Corrections, additions, deletions welcome:
