Specifies how date/time values are stored. When StorageTZ is set to UTC, the date/time is handled as Coordinated Universal Time (UTC). To denote that a date/time value refers to "abstract" time, meaning that the date/time is stored in the database as entered by the user without conversion or storage of the local time zone, omit the StorageTZ attribute
