How to find current date & time in dataweave? - datetime

I am converting a XML file to CSV file using dataweave , where i want current date & time from payload. So, how to get it?

use now
for eg. ProgramLastDate : now
or can be used`
[server.dateTime.format('yyyyMMddHHmmssSSSSs')]`

You can use "ProgramLastDate" : now as :string {format: "yyyy-MM-dd"} for getting system date and time, but as per your code I think you wanted to get date time from xml element Current_Effective_Time. If you are receiving Current_Effective_Time in "yyyy-MM-dd HH:mm:ss.SSS" format, You can use
ProgramLastDate : payload.ns0#Worker_Sync.ns0#Header.ns0#Current_Effective_Time as :datetime {format:"yyyy-MM-dd HH:mm:ss.SSS"} as :string {format:"dd-MM-yyyy"}
Hope this helps.

Format Date via Parameter

I have a DateTime variable (default formatting), and I would like to format it to a format to I receive from a string parameter.
I normally do something similar to: {myDate:yyyy-MM-dd}, and it works properly.
Now I have a lot of possible date formats and need to format according to the chosen one.
I have tried the following but returned garbage (ae0aor0aa):
string testFormat = "yyyy. MM. dd.";
{myDate:testFormat }
I have also tried to convert the date to string and back to date with ParseExact, but gave me an invalid date exception. NB: the date in myDate is valid, as I have checked it with the debugger.
Can you kindly advise?
Thanks to apc, it was easily solved by myDate.ToString(testFormat)

Date conversion handling YYYY-MM-DD HH:MM:SS.SSS

My source is a file and loading into SQL Server table. I'm working on a scenario where i have to convert a string '2019-04-02T21:24:00.065' to informatica datetime format.
I tried below expression but some times its failing due to we are not receiving milliseconds from our source file in few occasions.
IIF(NOT ISNULL(DATEFIELD),TO_DATE(SUBSTR (DATEFIELD, 0, 10) || ' ' || SUBSTR(DATEFIELD, 12, 12), 'YYYY-MM-DD HH24.MI.SS.US'),NULL)
I'm looking for a permanent fix to handle all types of datetime formats regardless of what we receive in the file.
Well... I'm sorry to say, but there is no magic component that will recognize all possible date and time formats (including e.g. verbal in swahili).
You will need to detect the format for yourself. You can use a DECODE function, like e.g.:
DECODE(True,
IS_DATE(your_input_port, 'DD/MM/YYYY'), TO_DATE(your_input_port, 'DD/MM/YYYY'),
...)
If you are completely sure that only seconds/milliseconds are the missing part, you can check for length, if less than 12, use RPAD to the second part of your SUBSTR with missing format, or you can use decode as suggested by #maciejg and write code for all possible date formats.
Thanks for your inputs guys. Since we are not sure which date format we are receiving , we decided to go with a simple fix for this. I have changed the target field to varchar and simply replacing the T with ' ' value since this a staging mapping.
Again thanks for your time and inputs.

Can't format the date using moment.js

Can't format the below date using moment.js, the below statement returns Invalid Date
moment('20171206T062406927Z').format('D-MMM-YYYY');
Please help me on this.
You need to tell moment which format your date string is in:
moment('20171206T062406927Z', 'YYYYMMDD[T]HHmmssSSSZ', true).format('D-MMM-YYYY');
Edit: updated as per #VincenzoC comment to ensure the timestamp is parsed in UTC
Also fix: use HH for 24-hour format (not hh), and pass a third true parameter to ensure the timestamp is parsed in strict mode.

How to format date and time in hbase?

moment.js and deprecated warning. timestamp to moment date object

I've read thru various posts on here in regards to similiar issues but none have solved my problem.
I manipulate the moment.js date object, and then store it as timestamp.
BUT, when I try to read in that timestamp again, I get that deprecated warning.
""Deprecation warning: moment construction falls back to js Date. This is discouraged and will be removed in upcoming major release. Please refer to https://github.com/moment/moment/issues/1407 for more info."
I've tried toDate(), format(), moment(myTimeStamp, 'ddd, DD MMM YYYY HH:mm:ss ZZ'); --> all generate the warning...
So, for example, my timestamp will look like this:
const timestamp = '1458586740000'
when I read that back and try to parse out the month/day/year, then the hour/min am/pm, etc... I need to get that timestamp into a moment.js object. Nothing is working for me. Any ideas.
How can I get this timestamp: '1458586740000', into a moment.js object so I can extract date date from it as I need?
EDIT: this is how I am storing the timestamp. So I would need to retrieve it from this.
let timeStamp = Moment(state[_Date])
.add({ hour: state[AMPM] === 'PM'
? +state[Hour] + 12
: state[Hour] ,
minute: state[Min] }).format('x')
The X token indicates a unix timestamp in seconds, and the x token indicates a unix millisecond timestamp (offset).
You appear to have a millisecond timestamp, so you would make a moment out of it by doing the following:
var a = moment('1458586740000', 'x')
It works without ' as well:
var a = moment(1458586740000, 'x')
You can also not specify the x and it should work:
moment(1458586740000)
Because you have a unix offset (milliseconds), not a unix timestamp (seconds), moment.unix is not what you want.
Then you can do the following:
a.format()
"2016-03-21T13:59:00-05:00"
Or you can use any of the other formatting tokens listed here to output whatever result you would like: http://momentjs.com/docs/#/displaying/format/
Based on the code you presented, I think you may be having problems because your timestamp is stored as a string (in ''). Parsing as a string causes an invalid date error, because it attempts to match ISO 8601 format and fails. Specifying that 'x' token will cause it to assume unix offset and work correctly.
