The xs:dateTime type combines Gregorian calendar dates with times. Its contents appear in the format CCYY-MM-DDThh:mm:ss, where CC is the century, YY is the year (00–99), MM is the month (01–12), DD is the day (01–31), hh is the hour (00–23), mm is the minute (00–59), and ss is the second (00–59, plus an optional decimal part). For years before 1, a negative sign may appear before the century. Acceptable xs:dateTime values include 1999-11-25T04:03:20, -0044-03-15T12:00:00, and 2020-01-01T18:47:49.

A time zone relative to Coordinated Universal Time, also known as Greenwich Time or UTC, may also be added. If there is a time zone, the format is ± hh:mm, wherein a plus or minus sign is followed by a two-digit value for hours, then a colon, and then a two-digit value for minutes. You can also use Z in place of the time zone, indicating UTC. Valid date/time combinations with a time zone include 1999-11-25T04:03:20+05:00, -0044-03-15T12:00:00-10:30, and 2020-01-01T18:47:49Z.
