From jFreeChart Millisecond to java.util.Date

Question

Regarding jFreeChart's Millisecond,

How can I get a java.util.Date object from a Millisecond instance?

From the docs, it only seems possible to subtract the milliseconds within Millisecond.

Since a Millisecond object is constructed like so:

  Millisecond ms = new Millisecond(
           millisec, 
           second,
           minute,
           hour,
           day,
           month,
           year);

I should be able to extract a valid Date object as well.

Edit

I need a Date object that gives back the exact time up to the millisecond accurate.

Does .getStart() provide this?

[ANSWER]: YES

Answer 1

Millisecond is like any other RegularTimePeriod in JFreeChart, so you can just

    Date d = ms.getStart();

or

    Date d = ms.getEnd();

depending on whether you want a date referring to the beginning or the end of your millisecond (same value either way).

See The JFreeChart API for more info.

EDIT: Adding code here since comments kill formatting:

    Millisecond ms = new Millisecond();
    System.out.println(ms.getStart().getTime());
    System.out.println(ms.getEnd().getTime());

will print the same millisecond twice.

Answer 2

As far as I can see the Millisecond Class represents the time period of a millisecond and I'd assume the the getStart and getEnd Methods inherited from RegularTimePeriod return (nearly) the same Date of which one is one you're looking for.

Answer 3

(my answer was late) Perhaps you could use this code:

java.util.Date date = new java.util.Date(freeMillis.getMillisecond());

edit: scrap that, freeMillis.getMillisecond() returns just a millisecond part.
