DateTime.toString

Converts this DateTime to a string.

This function exists to make it easy to convert a DateTime to a string for code that does not care what the exact format is - just that it presents the information in a clear manner. It also makes it easy to simply convert a DateTime to a string when using functions such as to!string, format, or writeln which use toString to convert user-defined types. So, it is unlikely that much code will call toString directly.

The format of the string is purposefully unspecified, and code that cares about the format of the string should use toISOString, toISOExtString, toSimpleString, or some other custom formatting function that explicitly generates the format that the code needs. The reason is that the code is then clear about what format it's using, making it less error-prone to maintain the code and interact with other software that consumes the generated strings. It's for this same reason that DateTime has no fromString function, whereas it does have fromISOString, fromISOExtString, and fromSimpleString.

The format returned by toString may or may not change in the future.
