>                 Key: CARBONDATA-4157
>                 URL: https://issues.apache.org/jira/browse/CARBONDATA-4157
>             Project: CarbonData
>          Issue Type: Bug
>          Components: data-load
>    Affects Versions: 2.1.0
>            Reporter: Yahui Liu
>            Priority: Minor
>
> # prepare one txt file contains 1 time data in daylight saving time, for example "1991-08-12 00:00:00"
>  # upload the file to one hdfs folder, for example /tmp/test_time
>  # create carbon table: create table test_time(t timestamp) stored as carbondata;
>  # create one external txt table with location to the data file folder: create table test_time_txt(t timestamp) location '/tmp/test_time';
>  # insert the data in txt table into carbon table: insert into test_time select * from test_time_txt; then query carbon table, result is:
>  # +------------------------+
> | t |
> +------------------------+
> | 1991-08-12 01:00:00.0 |
> +------------------------+
>  # load data directly into carbon table: load data inpath '/tmp/test_time' into table test_time options('fileheader'='t'); then query carbon table, result is:
>  # +------------------------+
> | t |
> +------------------------+
> | 1991-08-12 00:00:00.0 |
> +------------------------+
>  # same data file, insert into and load data give different result, and because "1991-08-12 00:00:00" is in daylight saving time, so most of the file format give "1991-08-12 01:00:00" as the result.
