Time

Elements of data type Time contain an indication of a particular time during a date. This data type describes a repeating portion of a day. That is, each time described (ignoring leap seconds) occurs once per calendar date. In the specification, it is required that a time data type be able to represent a specific period with indefinite precision. Milliseconds are the minimum required precision of the time data type.

Tags specified as type Time accept times in the following format:

hh:mm:ss.ffffff±HH:mm

A time represented using this data type must not be ambiguous with respect to morning and afternoon. That is, the time must occur once and only once each 24-hour period.

In addition, the Time data type must not be ambiguous with respect to location at which the time occurs. If unspecified, the time zone defaults to Coordinated Universal Time (UTC). Generally, use of a specific time zone in the representation is preferred. The time zone should always be specified to avoid ambiguous communication between clients and servers.
