  - toHumanDisplay
```
public String toHumanDisplay()
```
    Returns a human readable version of this date/time using the system local format.
    Note on time zones: This method renders the value using the time zone that is contained within the value. For example, if this date object contains the value "2012-01-05T12:00:00-08:00", the human display will be rendered as "12:00:00" even if the application is being executed on a system in a different time zone. If this behaviour is not what you want, use toHumanDisplayLocalTimezone() instead.
  - toHumanDisplayLocalTimezone
```
public String toHumanDisplayLocalTimezone()
```
    Returns a human readable version of this date/time using the system local format, converted to the local timezone if neccesary.
    
    See Also:
    
    for a method which does not convert the time to the local timezone before rendering it.
