Type:Date

http://semantic-mediawiki.org/wiki/Type:Date

The SMW datatype Date is used for data values that represent points in time. It is able to support dates throughout human history in a unified format, and it offers internationalisation options for supporting more languages. All dates and times refer to the "local time" of the server (or the wiki). A wiki may define what timezone this refers to by common conventions. For export, times are given without timezone information. However, time offsets to that local time are supported.
