I have a column which has date, time, and timezone info like this:
Sat, 20 Aug 2016 03:50:04 CDT Sun, 17 Sep 2017 16:51:46 CEST Mon, 09 Oct 2017 06:43:27 CET Thu, 28 Sep 2017 14:05:23 IST Thu, 05 Oct 2017 08:59:01 IDT Wed, 28 Jun 2017 17:10:22 CEST Mon, 18 Sep 2017 18:32:52 GMT Sat, 27 Aug 2016 07:06:22 MEST Sat, 06 Aug 2016 13:17:09 UTC Sat, 16 Jul 2016 23:53:02 PDT
I want to normalize these all to UTC.
I can strip off the leading 5 chars, and trailing timezone string, and they cast to datetime just fine... but my question is:
Does SQL Server have any built in function where I can pass in the datetime, the source timezone string e.g.
PDT and a target timezone string e.g.
UTC and it will handle the conversion?
I am thinking of something similar to what Oracle has:
FROM_TZ(YOUR_TIMESTAMP, 'UTC') AT TIME ZONE 'America/Dawson_Creek'
I am hoping to be able to do it without having to maintain a timezone offsets table to map the string values to an offset. I also don't want to hard-code the offsets in some big case-statement.
I am on sql server 2014, so I can't use the new
select * from sys.time_zone_info for timezone info that comes in 2016.
