Duration介绍

[英]$Id$

Created: [Apr 6, 2004]

Defines a DURATION iCalendar component property.

3.3.6.  Duration 
Value Name:  DURATION 
Purpose:  This value type is used to identify properties that contain 
a duration of time. 
Format Definition:  This value type is defined by the following 
notation: 
dur-value  = (["+"] / "-") "P" (dur-date / dur-time / dur-week) 
dur-date   = dur-day [dur-time] 
dur-time   = "T" (dur-hour / dur-minute / dur-second) 
dur-week   = 1*DIGIT "W" 
dur-hour   = 1*DIGIT "H" [dur-minute] 
dur-minute = 1*DIGIT "M" [dur-second] 
dur-second = 1*DIGIT "S" 
dur-day    = 1*DIGIT "D" 
Description:  If the property permits, multiple "duration" values are 
specified by a COMMA-separated list of values.  The format is 
based on the [ISO.8601.2004] complete representation basic format 
with designators for the duration of time.  The format can 
represent nominal durations (weeks and days) and accurate 
durations (hours, minutes, and seconds).  Note that unlike 
[ISO.8601.2004], this value type doesn't support the "Y" and "M" 
designators to specify durations in terms of years and months. 
The duration of a week or a day depends on its position in the 
calendar.  In the case of discontinuities in the time scale, such 
as the change from standard time to daylight time and back, the 
computation of the exact duration requires the subtraction or 
addition of the change of duration of the discontinuity.  Leap 
seconds MUST NOT be considered when computing an exact duration. 
When computing an exact duration, the greatest order time 
components MUST be added first, that is, the number of days MUST 
be added first, followed by the number of hours, number of 
minutes, and number of seconds. 
Negative durations are typically used to schedule an alarm to 
trigger before an associated time (see Section 3.8.6.3). 
No additional content value encoding (i.e., BACKSLASH character 
encoding, see Section 3.3.11) are defined for this value type. 
Example:  A duration of 15 days, 5 hours, and 20 seconds would be: 
P15DT5H0M20S 
A duration of 7 weeks would be: 
P7W
