timestamp-with-timezone

问题 I've been trying to convert each UTC time back to the appropriate local timezone using standard SQL in GBQ, but couldn't find a good way to do it dynamically because I might have tons of different timezone name within the database. I'm wondering if anyone has an idea? The table I have contains 2 different columns (see screenshot) 回答1: Below example is for BigQuery Standard SQL #standardSQL WITH `project.dataset.yourtable` AS ( SELECT 'Pacific/Honolulu' timezone, TIMESTAMP '2020-03-01 03:41:27

问题 I have a bunch of 1 minute returns in an xts object with the index being POSIXct and time zone being GMT. The returns are on NYSE so I would like to convert to the eastern time zone but I would like to take care of the daylight savings time properly. What is the best way of doing this? I am a bit confused between the EST timezone and the EDT timezone. I would like my times to convert properly to the NY time in winter and summer. 回答1: Use indexTZ<- and the America/New_York timezone > tail(SPY)
