    The ToDateTime operator converts the value of its argument to a DateTime value. For String values, the operator expects the string to be formatted using the ISO-8601 datetime representation: YYYY-MM-DDThh:mm:ss.fff(Z|((+|-)hh:mm)) See the Formatting Strings topic in the CQL Reference (Appendix B) of the CQL Specification for a description of formatting strings. In addition, the string must be interpretable as a valid DateTime value. If the input string is not formatted correctly, or does not represent a valid DateTime value, the result is null. As with Date and Time literals, DateTime values may be specified to any precision. If no timezone offset is supplied, the timezone offset of the evaluation request timestamp is assumed. For Date values, the result is a DateTime with the time components unspecified, except the timezone offset, which is set to the timezone offset of the evaluation request timestamp. If the argument is null, the result is null.
