DateTime

java.lang.Object
- jsimple.util.DateTime

```
public final class DateTime
extends java.lang.Object
```
This class represents a date/time, allowing the normal JSimple representation of time in millis (milliseconds since Jan. 1, 1970) to be mapped to and from month/day/year/day of week.
This class is based on the Joda DateTime class, though significantly simplified. In particular, only the ISO calendar (the "normal" one, used by most all the business world) is supported. Most Joda utility methods are removed, leaving the basics here--the field accessors and, importantly, the ability to convert to/from milllis and RFC 3339 text representation.
This class, as in Joda, is immutable. It uses Joda names and Joda/ISO conventions (month & day are 1-based and day of week starts with Monday = 1.
