zhao jintao updated KYLIN-3788:
-------------------------------
Description:
Hi, All team
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?
