Data Type

Data type code
Data type detail
Standard format for CIF date and time strings (see, consisting of a yyyy-mm-dd date optionally followed by the character 'T' followed by a 24-hour clock time, optionally followed by a signed time-zone offset. The IUCr standard has been extended to allow for an optional decimal fraction on the seconds of time. Time is local time if no time-zone offset is given. Note that this type extends the mmCIF yyyy-mm-dd type but does not conform to the mmCIF yyyy-mm-dd:hh:mm type that uses a ':' in place of the 'T' specified by the IUCr standard. For reading, both forms should be accepted, but for writing, only the IUCr form should be used. For maximal compatibility, the special time zone indicator 'Z' (for 'Zulu') should be accepted on reading in place of '+00:00' for GMT.
