Jared,

If that's true there has got to be something a little "strange" in the way that Oracle computes julian dates. Beacuse to_date(728,464,'J') returns 05-JUN-2718, where as to_char(sysdate,'J') returns 2,452,935. (comma's added for clarity)

I think what your boss really means is 'julian' date.

Does he also want his database in mauve?

Try this:

select to_date(bdate,'j') from paam;

That said, the dates in your example are about 700 years into the future.

Hi to all!

We have an old app that manages something that my boss calls: boolean dates.

He told me that exists an algorithm that manages dates as a boolean format.

We have several tables in this form:

Note: The following table: PAAM
has the field BDATE defined as NUMBER.

sql> select bdate from paam
sql> where rownum < 6

BDATE

    728464
    728434
    728403
    728495
    728283

now, I need to convert that format to an 'understandable' format to get the old data and old dates.

I'm looking (google-ing) for that subject but, without luck.

any ideas? help?, pls...

Thanks in advance

Regards!
JL
