zhao jintao commented on KYLIN-3788: ------------------------------------ I found that hour_start is 8 hours behind the real time.Day_start is also 8 behind the real time. I deal this bugfix. > Kylin's internal time zone conversions are various and confusing > ----------------------------------------------------------------- > > Key: KYLIN-3788 > URL: https://issues.apache.org/jira/browse/KYLIN-3788 > Project: Kylin > Issue Type: Bug > Components: REST Service, Web > Affects Versions: v2.5.2 > Environment: Huawei FI > Reporter: zhao jintao > Priority: Major > Labels: TimeZone > > I found that Kylin has a variety of time zone conversions inside, which is > confusing. In some code, the time zone is "GMT" when converting time, and > some code uses the time zone specified in the configuration file > ("TimeZone.getTimeZone("GMT")" ); > For Example: > in CubingJob.java, use TimeZone from configuration file: > format.setTimeZone(TimeZone.getTimeZone( > config.getTimeZone())), > but in TimeUtil.java, use GMT TimeZone:private static TimeZone gmt = > TimeZone.getTimeZone("GMT") > > When inport data from Kafka Streaming Data,kylin generate "Data_Start", > "Hour_Start" uses the GMT time zone, They are some time zones later than > the real time. Why not use the time zone specified in the configuration file? -- This message was sent by Atlassian JIRA (v7.6.3#76005)
