Duration and dtend

The ending date, dtend, overrides duration. If you specify both duration and dtend, the command ignores duration.

Duration strings can be used in three parameters: duration, alarmPopup and alarmStart.

Specify the duration in iCal format. For example:

• P1Y2M3DT1H30M10S represents a duration of 1 year, 2 months, 3 days, 1 hour, 30 minutes, 10 seconds

• PT1H30M represents a duration of 1 hour, 30 minutes

• P1D represents a duration of 1 day

• PT15M represents a duration of 15 minutes

Notice that the T in the string separates the date information from the time information.
