UTC在因帕拉

Question

在因帕拉pst转换一些我得到不正确的数据，同时从UTC转换为PST.When时间戳我在蜂巢上运行相同的查询，我得到正确的数据，但在黑斑羚PST转换是没有做正确的一些日期。

帕拉：

select from_utc_timestamp('2006-08-30 08:00:00','PST') 
2006-08-30 01:00:00 

蜂巢：

select from_utc_timestamp('2006-08-30 08:00:00','PST') 
2006-08-30 00:00:00 

为了克服是否有任何其它的方式来UTC转换到PST以下时区转换

Answer 1

使用的黑斑羚。 from_utc_timestamp（时间戳，字符串时区）

timezone : 
for Eastern Time: America/New_York or EST5EDT 
for Central Time: America/Chicago or CST6CDT 
for Mountain Time: America/Denver or MST7MDT 
    Phoenix won't observe daylight saving time: America/Phoenix 

for Pacific Time: America/Los_Angeles or PST8PDT 
for Alaska Time: America/Anchorage or America/Juneau 
for Hawaii Time: America/Adak or EST5EDT 
    Honolulu won't observe day light saving time: Pacific/Honolulu 

select from_utc_timestamp('2017-03-11 13:41:22.084','America/Los_Angeles') 
    2017-03-11 05:41:22.084000000           

select from_utc_timestamp('2017-03-12 13:41:22.084','America/Los_Angeles') 
    2017-03-12 06:41:22.084000000          

select from_utc_timestamp('2017-11-03 13:41:22.084','America/Los_Angeles') 
    2017-11-03 06:41:22.084000000          

select from_utc_timestamp('2017-11-04 13:41:22.084','America/Los_Angeles') 
    2017-11-04 06:41:22.084000000
