timestamp field
Hi,
I have on my schema
<field name="timestamp" type="date" indexed="true" stored="true"
default="NOW" />
This field is returned as
<date name="timestamp">2010-08-11T10:11:03.354Z</date>
For an article added at 2010-08-11T11:11:03.354Z!
And the server has the time of 2010-08-11T11:11:03.354Z...
This is a w2003 server using solr 1.4.
Any guess of what could be wrong here?
Thanks,
Frederico

For what it's worth, London and the rest of the UK is currently
observing British Summer Time (called Daylight Savings Time in other
parts of the world) which is why we appear to be UTC+1 between the
last Sunday in March and the last Sunday in October.

Hi Jan,
Dah, I didn't know that :(
I always thought it used the servertime.
Anyway,just out of curiosity, the hour is UTC but NOT the time in London right now.
London is UTC+1 (same as here in Portugal) :).
So, London solr users should have the same "problem".
Well, I must be careful when using this field.
Thanks for your answer,
Frederico

Hi,
Which time zone are you located in? Do you have DST?
Solr uses UTC internally for dates, which means that "NOW" will be the time in London right now :) Does that appear to be right 4 u?

Hi,
Which time zone are you located in? Do you have DST?
Solr uses UTC internally for dates, which means that "NOW" will be the time in London right now :) Does that appear to be right 4 u?
