Unanswered: Timezone/Daylight Saving Time Formula: Siebel
I'm developing a Siebel Analytics report and one of the requirements is to convert datestamp, which is in GMT, to Eastern Time U.S.
I understand that it is Eastern time is GMT -5 from second sunday of March at 2am to first sunday of November at 2am and GMT -4 any months outside of that.
I'm new with Siebel Analytics, and I'm not sure in how to construct an SQL formula to convert the datestamp.
I hope you can be an assistance to my delema.
Thanks in advance!
You can query the needed offset using the TZ_OFFSET() function:
SELECT TZ_OFFSET('US/Eastern') FROM DUAL;
It will correctly apply the DST rules (based on the time zone of your server)
Btw: what is "datestamp"?
In Oracle you either have DATE or TIMESTAMP, but there is no DATESTAMP data type.
Edit: this example shows how to convert from one timezone to another:
So you should be able to simply select your timestamp column using:
SELECT timestamp_column AT TIME ZONE 'US/Eastern'
