I am trying to convert input mesage's timestamp (ISO 8601) to Shanghai timezone specific.
Example:
Input (for instance, pst time, utc offset -7) : 2010-05-20T07:21:52.866-07:00
Output (must be shanghai timezone, utc offset +8 ): 2010-05-20T22:21:52.866+08:00
I know I can get this done using the below ESQL. But wondering if there is any simpler statement using cast/function to avoid string manipulation ESQL statements (last but 2/3 statements).
SET OutputRoot = InputRoot;
DECLARE inTime GMTTIMESTAMP;
DECLARE outTime GMTTIMESTAMP;
DECLARE inTimeChar CHARACTER;
DECLARE outTimeChar CHARACTER;
SET inTimeChar = InputRoot.XML.message.Timestamp;
SET inTime = CAST(inTimeChar AS GMTTIMESTAMP FORMAT 'IU');
SET outTime = EVAL('inTime + INTERVAL ''8'' HOUR');
SET outTimeChar = CAST(outTime AS CHARACTER FORMAT 'yyyy-MM-dd''T''HH:mm:ss');
SET outTimeChar = outTimeChar || '.000+08:00';
SET OutputRoot.XML.message.Timestamp = outTimeChar;

You'd probably be better off using a simple Java procedure taking input string as timestring, simple time format string, input time zone, output simple time format string and output time zone. The response would then be your formatted time string...
2010-05-20T21:21:52.866-07:00 => 2010-05-21T04:21:52.866+00:00
2010-05-20T22:21:52.866+08:00 => 2010-05-20T16:21:52.866+00:00
Notice that your calculation doesn't match...
2010-05-21T12:21:52.866+08:00 => 2010-05-21T04:21:52.866+00:00
As you add the offset from GMT to Local you have to subtract the offset from local to GMT => PST+7 = GMT and add the offset from GMT to local Shanghai = GMT +8, => +7 from PST to GMT and +8 from PST to Shanghai => Shanghai = PST +15
Have fun

If +08:00 is your Broker local timezone, you can code as below; if not, then I think there is no other easier way.
DECLARE inTime GMTTIMESTAMP;
DECLARE outTime TIMESTAMP;
DECLARE inTimeChar CHARACTER;
DECLARE outTimeChar CHARACTER;
SET inTimeChar = InputRoot.XML.message.Timestamp;
SET inTime = CAST(inTimeChar AS GMTTIMESTAMP FORMAT 'IU');
SET outTime = CAST(inTime AS TIMESTAMP); ==> the result value is source value plus the local time zone
SET outTimeChar = CAST(outTime AS CHARACTER FORMAT 'yyyy-MM-dd''T''HH:mm:ss ZZZ'); |

| How does it fail to work if you just add an interval of 8 hours to the GMTTIMESTAMP? |

mqjeff, I didn't follow you, Is this question for me? My code is not failing, and its working the way I wanted the output.

fjb_saper, all I want to do is to represent the output time always specific to shanghai timezone. For example, if I get the time as '2010-05-20T07:21:52.866-07:00', then add 15 hours, and result should be '2010-05-20T22:21:52.866+08:00'. Second example, if I get input time as '2010-07-18T22:45:13.003-05:00', then add 13 hours, and result should be '2010-07-19T11:45:13.003+08:00'
My above ESQL is working good for my logic.

This is an old flow which using ESQL for lot of other transformations. I just want to add this small logic in the same compute node. Not planning for a JCN.

NO, my local timezone is NOT+08:00

The way I would solve this problem, of converting a timestamp from current timezone to GMT +8 timestamp, would be to convert the timestamp to GMTTIME and then add an INTERVAL of 8 hours.
I don't see any particular need to solve this problem by casting anything as character and then parsing it again. |

Hi! Can I ask for help? I want to know why my code is not working? It still provide the ccyy-mm-dd-hh.mm.ss.mmmmmm
DECLARE inputStringDate CHARACTER FACTN.FACTN_TIMESTAMP;
DECLARE referralTimestamp GMTTIMESTAMP;
DECLARE patternInput GMTTIMESTAMP;
SET referralTimestamp = CAST(inputStringDate AS GMTTIMESTAMP FORMAT 'yyyy-mm-dd-hh.mm.ss'||'.000+08:00');
SET patternInput = CAST(referralTimestamp AS GMTTIMESTAMP FORMAT 'yyyymmdd'||'T'||'hhmmss'||'GMT');
SET policyTransactionDetailRef.ReferralTimestamp = patternInput; |

hi...instead of reopening a decade old thread you are better off starting a new one with a clear problem description and may be link the old thread if approprate so.
If you are just attempting to add 8 hours look at the below comment,
