How does one convert a particular date to milliseconds? Milliseconds is a duration.

I can tell you how many milliseconds are in one day (1 day = 24 hours = 86,400,000 milliseconds), I can tell you how many milliseconds there are in 24 June, 2011, the same number as in 17 February, 1993 - every day has the same number of milliseconds.

I can tell you how many milliseconds there are between 5 August 2003 and 14 April 2011 - is that what you're looking for?

Well this hasn't happened in forever. Welcome LMP - wonder why you did not have to put what version you are using. Thought that was a requirement when registering......

Sorry if my question was wrong.

I am doing a Java rewrite to Web focus.

In java the milliseconds of a date is retrieved using Date.getTime() function. The input to this function is a date of format yyyy-mm-dd.
I am expecting something similar in webfocus.

By the way i am using WF version 7.6.9

Thanks,
LMP

Give me an example of a result of the Date.getTime() function.

getTime() Returns the number of milliseconds since January 1, 1970, 00:00:00 GMT represented by this Date object.

Try something like this:

-* File datedif2.fex

-SET &ECHO=ALL;

DEFINE FILE CENTORD
HDTTM0/HYYMDs = HINPUT(14,'19700101000000', 8, 'HYYMDs');
HDTTM1/HYYMDs = HDTTM(ORDER_DATE, 8, 'HYYMDs');
HDIFF_MS/D15  = HDIFF(HDTTM1, HDTTM0, 'millisecond', 'D15');
END

TABLE FILE CENTORD
PRINT
HDTTM0
HDTTM1
HDIFF_MS
END


You may have to adjust 1970/01/01 00:00:00 by four hours because Java is based on GMT - just compare a date to the results in your Java program.

WHERE RECORDLIMIT EQ 1
END


For some reason, the base date needs to be near 1970/01/02/20:00:00 to get close to your value of 1,302,494,520,000. My code gives 1,302,494,400,000. So the base date needs to be tweaked by some minutes...
