I stored date in database but whenever i am fetching then its format change
getting date - 2018-07-31T06:48:01.649Z
stored date in db - 2018-07-31 12:18:01.649
here is my code
var timee = result.created;
By default, dates are stored in UTC in MongoDB so you are seeing the difference in the time zone of stored and retrieved dates.
new Date() returns the current date as a Date object. The mongo shell wraps the Date object with the ISODate helper. The ISODate is in UTC.
You can read the MongoDB specification here.
There are several approaches that you can apply. Either convert the date to UTC timezone before saving it or convert into locale time zone after loading the date.
new Date(ISODate().toString() + 'UTC')
ISODate("2018-08-01T11:39:39Z")
and to replace the T and Z with an empty space using the javascript.
dateString.replace("T", " ").replace("Z", " ");

I am storing a date in mongodb using mongose with the help of moment js.
I am creating the date object from a date string which is in the format MM/DD/YYYY.
below is how i assign the date
const startDate = momentTz(
data.startDate,
"MM/DD/YYYY",
"Asia/Kolkata"
).startOf("day");
but ever time I assign this date object to the mongoose model while creating a document it is storing as 2022-11-30T18:30:00.000+00:00 ie, the time is being automatically set to 18:30.
how can i set this to the start of the day.
Use this one:
const startDate = momentTz(
data.startDate,
"MM/DD/YYYY",
"Asia/Kolkata"
).startOf("day").toDate();
MongoDB stores Date values as UTC times - always and only. It is the client responsibility to display the date/time in local time zone and format.
MongoDB stores dates as BSON type 9, which stores the number of milliseconds since 1970-01-01 00:00 UTC.
18:30 UTC is midnight in Kolkata, so that date/time is correctly showing the start of the day 2022-11-31 IST.
It is up to the client program to convert from UTC to a different timezone if that is desired.
I have a Postgres database. In a table I have a column of type „date“.
I try to insert into this db with node express
Let myDate = "2022-03-03";
DB.query("INSERT INTO mytable (mydate) VALUES ($1)", [myDate]);
But the date in the database is then "2022-03-02". Looks like node is doing some kind of date to datetime conversion and then depending on the timezone reconvert it (because my timezone is 1h behind UTC)
So who can explain what is going on and how to handle this correct?
I have a column where timestamp is 5/23/2022 8:45:34 PM. I want to create a new column with same data as old column but in UTC format 'yyyy-MM-dd HH:mm:ss' and this new datetime format is 7 hours behind UTC (UTC-7)
I tried doing in azure data factory derived column using toTimestamp before it converts to UTC but it always fail.
toTimestamp(column_name,'yyyy-MM-dd HH:mm:SS')
but it did not work and the result always NULL.
Can anyone help this data conversion to UTC ?
The reason you are getting null values for the newly added columns is because the format you specified in the toTimestamp() function is incorrect. The following is the sample data that I used to reproduce this issue. The date column here is of type String.
While using Derived column in the dataflow to create a new date column of timestamp type, write toTimestamp(date, 'MM/dd/yyyy hh:mm:ss a', 'UTC') expression as the value for this new column. Here, date is the column you want to convert to new date column and MM/dd/yyyy hh:mm:ss a is the format of the values in date column (a represents the AM/PM). You can also pass time zone value like UTC, GMT etc. which is optional.
The following is what the result looks like, with a new column of timestamp type. You can use this resulting data to perform further conversions in dataflow.

I'd like to transform CSV file using ADF Mapping data flow.
I have a string column containing data in ticks date format that I want to transform into Date time.

I've tried to convert the ticks value to UNIX Epoch timestamp and used the below expressions which I got from different thread but I'm getting null values.
toTimestamp(toLong(toInteger(toString(byName('ticks_date')))),'yyyy-MM-dd HH:mm:ss')
toTimestamp(seconds(toInteger(toString(byName('ticks_date')))),'yyyy-MM-dd HH:mm:ss')
I'm a newbie to ticks format and stuck here couple of days.
Appreciate if someone can guide me to resolve the issue.
There are two approaches you can follow:
Create datetime object with a specific value of ticks
DateTime myDate = new DateTime(numberOfTicks);
String test = myDate.ToString("MMMM dd, yyyy");
Much simpler manner
DateTime dt = new DateTime(633896886277130000);
Which may give output like below
"9/27/2009 10:50:27 PM"

I have tried to insert date into the postgresql in 'dd.mm.yyyy' format.
First inserted the string type, then the date type
moment(new Date()).format('DD.MM.YYYY') but in database format always like 'yyyy-mm-dd'
What can I do?
Plesase, help
