The ConvertsToDateTime operator returns true if the value of its argument is or can be converted 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 false. 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. If the argument is null, the result is null.
