Description

The `Values.parseString(String)` method that returns a `SchemaAndValue` is not able to parse a string that contains a time or timestamp literal into a logical time or timestamp value. This is likely because the `:` is a delimiter for the internal parser, and so literal values such as `2019-08-23T14:34:54.346Z` and `14:34:54.346Z` are separated into multiple tokens before matching the pattern.

The colon can be escaped to prevent the unexpected tokenization, but then the literal string contains the backslash character before each colon, and again the pattern matching for the time and timestamp literal strings fails to match.

This should be backported as far back as possible: the `Values` class was introduced in AK 1.1.0.
