Property Name

DTSTAMP

Purpose

In the case of an iCalendar object that specifies a "METHOD" property, this property specifies the date and time that the instance of the iCalendar object was created. In the case of an iCalendar object that doesn't specify a "METHOD" property, this property specifies the date and time that the information associated with the calendar component was last revised in the calendar store.

Value Type

DATE-TIME

Property Parameters

IANA and non-standard property parameters can be specified on this property.

Conformance

This property MUST be included in the "VEVENT", "VTODO", "VJOURNAL", or "VFREEBUSY" calendar components.

Description

The value MUST be specified in the UTC time format.

This property is also useful to protocols such as [2447bis] that have inherent latency issues with the delivery of content. This property will assist in the proper sequencing of messages containing iCalendar objects.

In the case of an iCalendar object that specifies a "METHOD" property, this property differs from the "CREATED" and "LAST- MODIFIED" properties. These two properties are used to specify when the particular calendar data in the calendar store was created and last modified. This is different than when the iCalendar object representation of the calendar service information was created or last modified.

In the case of an iCalendar object that doesn't specify a "METHOD" property, this property is equivalent to the "LAST-MODIFIED" property.

Format Definition

This property is defined by the following notation:

 dtstamp    = "DTSTAMP" stmparam ":" date-time CRLF

 stmparam   = *(";" other-param)

Need to test your iCalendar feeds? The iCalendar Validator provides developers and testers a method to validate their iCalendar feeds, which can take data from either a URL, file or text snippet and compare it against the RFC 5545 specification.  We believe we have one of the best iCalendar validation tools available on the internet.
