11 Based on the ISO 8601:2004 standard (described in a PDF Wikipedia
|
|
|
12 http://isotc.iso.org/livelink/livelink/4021199/ISO_8601_2004_E.zip?
|
|
|
13 func=doc.Fetch&nodeid=4021199), which has functions for parsing almost
|
|
|
14 every date/time format specified.
|
|
|
15
|
|
|
16 The ones they don't parse are intervals, durations, and recurring
|
|
|
17 intervals, because I got too lazy to implement them. The functions
|
|
|
18 (iso8601Time, iso8601Date, and iso8601) update a Date passed instead
|
|
|
19 of a Time, as does the current iso8601, because that's too limited
|
|
|
20 a format. One can always convert to a Time if necessary, keeping
|
|
|
21 in mind that information loss might occur if the Date is outside the
|
|
|
22 interval Time can represent.
|
|
|
23
|
|
|
24 In addition, because its dayOfWeek function only works for 1900-3-1 to
|
|
|
25 2100-2-28, it would fail by a day or two on ISO week dates outside that
|
|
|
26 interval. (Currently it asserts outside 1901-2099.) If somebody knows a
|
|
|
27 good algorithm which would fix that, by all means submit it.
|
|
|
28
|
|
|
29 Another thing it doesn't do is conversions from local time to UTC if the
|
|
|
30 time parsed starts with a 'T'. A comment in doIso8601Time() explains why.
|
|
|
31
|
|
|
32 Because the Date struct has no support for time zones, the module just
|
|
|
33 converts times with specified time zones into UTC. This leads to
|
|
|
34 behaviour which may or may not be a bug, as explained in a comment in
|
|
|
35 getTimeZone().
