13 How long is a Swatch .beat? In short, we have divided up the virtual and
14 real day into 1000 I<beats>. One Swatch beat is the equivalent of 1
15 minute 26.4 seconds. That means that 12 noon in the old time system is
16 the equivalent of @500 Swatch .beats.
17
18 Okay, so how can a surfer in New York, or a passenger on a transatlantic
19 flight know when it is @500 Swatch .beats in Central Europe for example?
20 How can the New York surfer make a date for a chat with his cyber friend
21 in Rome? Easy, Internet Time is the same all over the world.
22
23 How is this possible? We are not just creating a new way of measuring
24 time, we are also creating a new meridian in Biel, Switzerland, home of
25 Swatch.
26
27 Biel MeanTime (BMT) is the universal reference for Internet Time. A day
28 in Internet Time begins at midnight BMT (@000 Swatch .beats) (Central
29 European Wintertime). The meridian is marked for all to see on the
30 facade of the Swatch International Headquarters on Jakob-Staempfli
31 Street, Biel, Switzerland. So, it is the same time all over the world,
32 be it night or day, the era of time zones has disappeared.
33
34 The BMT meridian was inaugurated on 23 October 1998 in the presence of
35 Nicholas Negroponte, founder and director of the Massachusetts Institute
36 of Technology`s Media Laboratory.

41 parse_time
42 Parses a .beat time and returns a DateTime object. The object uses the
43 current date for its date and will have UTC set as its timezone. Feel
44 free to use 'set' to convert to your local time.
45
46 my $first = DateTime::Format::IBeat->parse_time( '@765' );
47 print $first->datetime; # 2003-04-01T17:21:36
48
49 $first->set_time_zone( "Australia/Sydney" );
50 print $first->datetime; # 2003-04-02T03:21:36
51
52 Note that the leading @ is optional. Also, if using direct strings, and
53 leading @s, be careful to not have it interpolate it as an array by
54 accident.
55
56 parse_date
57 Parses an .beat date and returns a "DateTime" object representing that
58 date.
59
60 my $dt = DateTime::Format::IBeat->parse_date('@d01.04.03');
61 print $dt->ymd('.'); # "2003.04.01"
62
63 Note: this assumes the number of .beats elapsed in the day to be 0,
64 thus it will appear to be returning the day before. If you display a
65 full time with it, you will find it's at UTC rather than BMT (+0100),
66 thus 11pm the day before. The important thing to remember is that it is
67 an accurate conversion to the usual notation, despite appearances.
68
69 parse_datetime
70 Parses an ibeat datetime string and returns a "DateTime" object
71 representing that datetime.
72
73 my $dt = DateTime::Format::IBeat->parse_datetime(
74 '@d01.04.03 @765');
75 print $dt->datetime; # "2003-04-01T17:21:36"
76
78 format_time
79 Given a DateTime object, returns a string representating that time in
80 ibeats.
81
82 format_date
83 Given a DateTime object, returns a string representating that date.
84
85 format_datetime
86 Given a Datetime object, returns a string representating that date and
87 time in .beats format.

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