I have an issue.
I don't find how to convert my column to the right timezone. example below :
SELECT
date AS date, --> how to convert to 'europe/paris' timezone
FROM tableName
if you have an idea.
Thanks
Use AT TIME ZONE:
select now() at time zone 'Europe/Paris';
Output:
_col0
2022-11-11 12:00:59.405 Europe/Paris

I have a dataset with timestamp strings like '2022-05-25T13:31:22.566-0400' I would like to convert it to '%Y-%m-%dT%H:%i:%s' format but adjusting for the timezone difference.
So for the above, how convert '2022-05-25T13:31:22.566-0400' to '2022-05-25T17:31:22.566' in Presto?
Thanks a lot!
You can use from_iso8601_timestamp to parse date, then cast to timestamp to remove timezone info (will be treated as UTC, at time zone 'UTC' should have the same effect) and use date_format to get required output format:
select date_format(
cast(from_iso8601_timestamp('2022-05-25T13:31:22.566-0400') as timestamp),
'%Y-%m-%dT%H:%i:%s')
Or
select date_format(
from_iso8601_timestamp('2022-05-25T13:31:22.566-0400') at time zone 'UTC',
'%Y-%m-%dT%H:%i:%s')
Output:
_col0
2022-05-25T17:31:22
I'm new to Big Query,
I want to convert the following date-time to UTC timezone.
DateTime format "2021-07-03T23:59:00+04:00[Asia/Dubai]" to UTC.
Thank you.
You just need to convert it to TIMESTAMP() without specifying any timezone (since it automatically sets the datetime at UTC) and then convert it back to DATETIME():
SELECT
your_datetime,
DATETIME(TIMESTAMP(your_datetime)) AS datetime_utc
FROM
<your_table>
OUTPUT:
your_datetime datetime_utc
------------------------- -------------------
2021-07-03T23:59:00+04:00 2021-07-03T19:59:00
I have been able to convert a TIMESTAMP field that is in UTC to CST using:
SELECT
TIMESTAMP(started_at) AS UTC,
TIMESTAMP_SUB(TIMESTAMP (started_at), INTERVAL 5 HOUR) AS CST
This returns:
ROW
UTC
CST
1
2020-05-17 13:07:22 UTC
2020-05-17 08:07:22 UTC
The second TIMESTAMP displays the correct date and time but UTC still shows. What is the simplest way to replace 'UTC' with 'CST' or, alternatively, remove 'UTC' altogether since I don't need the designation in the field itself?
You can use a plain sql replace function inline
select replace(TIMESTAMP_SUB(TIMESTAMP (started_at), INTERVAL 5 HOUR), 'UTC','') AS CST
The above searches the result of your expression (provided in your question) for 'UTC' and replaces it with nothing ''. You could also replace it with 'CST' as you noted.
Obligatory warning: I believe your query will only be correct half the year as long as DST is observed? You might want to look into sys.time_zone_info and its reference on the MSDN.
My advise is to convert the timestamp to a datetime local value:
select datetime(started_at, 'America/Chicago') as started_at_cst
Note that the time zone is not stored in the data value. Instead, this encodes the value in the string.
If you want to include the time zone value, I have found that the best approach is to use a string (argghh!). The following constructs a string:
format_timestamp('%F %X%z', started_at, 'America/Chicago') as started_at_str
which can be converted easily into a timestamp for date/time calculations:
timestamp(started_at_str)
I am using Redshift and am looking to extract the time from the timestamp.
Here is the timestamp: 2017-10-31 23:30:00
and I would just like to get the time as 23:30:00
Is that possible?
In Redshift you can simply cast the value to a time:
the_timestamp_column::time
alternatively you can use the standard cast() operator:
cast(the_timestamp_column as time)
Please go through this link
http://docs.aws.amazon.com/redshift/latest/dg/r_Dateparts_for_datetime_functions.html
timezone, timezone_hour, timezone_minute
Supported by the DATE_TRUNC function and the EXTRACT for time stamp
with time zone (TIMESTAMPTZ)
Examples is here
select extract(minute from timestamp '2009-09-09 12:08:43');
select extract(hours from timestamp '2009-09-09 12:08:43');
I need to cast a DATE value in a query to a TIMESTAMP WITH TIME ZONE, but currently I'm getting the TimeZone Region ('Europe / Paris') which is not valid to be used by EF.
For example, when doing this:
select CAST(FECHA AS TIMESTAMP WITH TIME ZONE) from test;
I currently get this output:
07/03/14 09:22:00,000000000 EUROPE/PARIS
But I need it to be like:
07/03/14 09:22:00,000000000 +01:00
Any idea how to accomplish this?
You can cast the DATE to a TIMESTAMP, then use FROM_TZ to convert this timestamp to a timestamp with time zone:
SQL> SELECT from_tz(CAST (SYSDATE AS TIMESTAMP), '+01:00') tz FROM dual;
TZ
-------------------------------------------------
07/03/14 09:47:06,000000 +01:00
With #Vincent Malgrat solution you need to get the TIMEZONE_HOUR and then, format it to use in your query. I don't know if there is any chance to make it automatically.
I can suggest you to nest some functions. It is not the cleanest solution but it works for me
SELECT TO_TIMESTAMP_TZ(TO_CHAR(CAST(FECHAHORA AS TIMESTAMP WITH TIME ZONE), 'DD-MM-YY HH24:MI:SS TZH:TZM'), 'DD-MM-YY HH24:MI:SS TZH:TZM' )FROM TEST;
And the result will be something like
03/03/14 09:58:02,000000000 +01:00
Regards!
Use
ALTER SESSION SET TIME_ZONE = '+01:00';
before your SELECT
