Hi Mario,

As a quick guess, I'd suppose that those two date strings are being parsed by slightly different code. If someone knows for sure, they can chime in.

I might be able to look at it some more later. At the minute, do you have a sufficient work-around/understanding to make progress?

Cheers,

Jim

Thank you very much Jim.

Yes, I am in Tokyo right now so it is UTC/GMT +9 for us here.

For some reason, this works:

intime BETWEEN '2011/03/11 23:01:26' and '2011/03/11 23:09:12'

and returns the correct desired results even without the 'Z'.

Still can not understand why this gives the wrong results:

intime BETWEEN '2011-03-11 23:01:26' and '2011-03-11 23:09:12'


Mario.

    Hi Mario,

    From a quick peek at the docs for ECQL(*), you can specify a
    'date-time' by giving the date, the letter 'T', and then the UTC time.

    Example filters:
    dtg BETWEEN '0000-01-01T00:00:00.000Z' AND '9999-12-31T23:59:59.000Z'
    or
    dtg DURING 2010-08-08T00:00:00.000Z/2010-08-08T23:59:59.000Z

    By chance is your timezone 9 hours off of UTC?  The code for
    dateParse delegates to SimpleDateFormat.parse here:
    
https://github.com/geotools/geotools/blob/master/modules/library/main/src/main/java/org/geotools/filter/function/FilterFunction_dateParse.java#L73-75.


    Cheers,

    Jim

    Hello,

    I am having strange results whenever I do time filters with
    similar to the  CQL:

    intime > dateParse('yyyy-MM-dd HH:mm:ss','2011-03-11 22:23:31')
     and intime < dateParse('yyyy-MM-dd HH:mm:ss','2011-03-11 22:58:51')

    wherein I would get features that are in the '2011-03-11
    13:00:00' time range. I tried also the BETWEEN ... AND keywords
    and got similar strange results.

    Is there a proper way of writing CQL filters with timestamps
    beside the one I am doing?

    Thanks.

    Mario.
