Date Faceting or Range Faceting doesn't take timezone into account. -------------------------------------------------------------------
Key: SOLR-2690 URL: https://issues.apache.org/jira/browse/SOLR-2690 Project: Solr Issue Type: Bug Affects Versions: 3.3 Reporter: David Timezone needs to be taken into account when doing date math. Currently it isn't. DateMathParser instances created are always being constructed with UTC. This is a huge issue when it comes to faceting. Depending on your timezone day-light-savings changes the length of a month. A facet gap of +1MONTH is different depending on the timezone and the time of the year. I believe the issue is very simple to fix. There are three places in the code DateMathParser is created. All three are configured with the timezone being UTC. If a user could specify the TimeZone to pass into DateMathParser this faceting issue would be resolved. Though it would be nice if we could always specify the timezone DateMathParser uses (since date math DOES depend on timezone) its really only essential that we can affect DateMathParser the SimpleFacets uses when dealing with the gap of the date facets. Another solution is to expand the syntax of the expressions DateMathParser understands. For example we could allow "(?timeZone=VALUE)" to be added anywhere within an expression. VALUE would be the id of the timezone. When DateMathParser reads this in sets the timezone on the Calendar it is using. Two examples: - "(?timeZone=America/Chicago)NOW/YEAR" - "(?timeZone=America/Chicago)+1MONTH" I would be more then happy to modify DateMathParser and provide a patch. I just need a committer to agree this needs to be resolved and a decision needs to be made on the syntax used Thanks! David -- This message is automatically generated by JIRA.
